It is not known if Radium can be absorbed through your skin. Radium is a radioactive substance found in nature that can have adverse health effects under certain conditions. Unlike other chemical elements, radium is unnecessary for living organisms and may cause various health effects to the exposed individual. Aged lume has often dried out and turned brittle, so that’s certainly a risk when you want to relume the hands, for example. Plutonium is at the heart of one of the most devastating weapons the world has ever seen — thousands were killed when the atomic bombs were dropped on Hiroshima and Nagasaki during World War II.. However, every watch is unique so you’ll need to test that particular watch. As the particles are emitted from the radium markers in every direction, only a fraction of the total dose emitted is actually absorbed by the person wearing or working on the watch. Radium occurs throughout Earth’s crust but occurs in unusually high levels in certain locations such as uranium mines and fossil-fuel driven factories. Radium is a highly radioactive alkali metal. Some of this Radium will then leave the body in a person’s feces and urine on a daily basis and some may remain in the bones throughout the person’s lifetime. Radium has received a reputation of being a very dangerous element. Pierre and Marie Curie first identified the radium element in 1898, but it wasn’t until 1910 that Marie successfully isolated a sample of it to work with. As opposed to radioactive iodine which gets taken up by the thyroid. There’s a way to handle it safely with the proper protective clothing and procedures. Rings through to Massachusetts State Police. It was not only the dial painters that became ill. It may be given to you for other reasons. Atomic weight (average mass of the atom): 226 4. And thats not counting the alpha radiation. How is radium used today? Nowadays, Super-LumiNova, which is entirely non-radioactive and non-toxic, is the most used lume in watchmaking. Radium is highly radioactive, and has a half life of thousands of years, so a radium-based watch is as radioactive today as it was when it was first made. Would my grandfather’s 1967 Accutron contain radium? When putting my camera over it it starts to flash from the high radiation so always be careful and it is not recommended to tamper with the paint because it can still be hazardous and contaminate large areas. When ingested, radium is particularly dangerous: "Chemically, it behaves very much like calcium," said Jorgensen. Did Bulova use radium in its watches and if so, when was that practice discontinued? It takes about 7 tons of ore just to produce a single gram of radium. Yet, at the time, very few scientists or advertisements discussed or even referred to its physical properties. Do not include sensitive information, such as Social Security or bank account numbers. Radium is so radioactive that it can glow and at one point it was used to make luminous paints, though now that is considered too dangerous. But it’s also not as life-threatening as many claim it to be. Many vintage watches have radium lume on the dial and in the watch hands. I try to keep away from the dial as much as possible because it’s very easy to accidentally remove varnish or lettering/markings. Ra-226 is a radioactive substance found in nature. When radium decays, ionizing radiation They licked their brushes with luminous paint hundreds of times a day and ingested radium every time they did so. Higher doses of Radium have been shown to cause effects on the blood (anemia), eyes (cataracts), teeth (broken teeth), and bones (reduced bone growth). Low levels of exposure to Radium are normal, and there is no evidence that exposure to low levels is harmful. Radioactivity was new and exciting. You’ll be more exposed because you’ll likely wear a watch for more than 30 minutes at a time. Every now and again, there’ll be a uranium atom that undergoes spontaneous fission. I bought a NOS watch by CWC. Alpha particles are highly dangerous inside the body, though, because it kills and mutates cells. Most importantly, they were forbidden to point the tip with their lips, and they avoided to ingest or inhale the luminous paint. Traces of radium 226 can be found in uranium ore – of the order of one atom per three million. How much do you agree with the following statements in the scale of 1, Strongly Disagree, to 5, Strongly Agree? Omega stopped using radium around 1963. In the early 1900s, the dials and hands of nearly all timepieces were painted with this radioluminescent paint. It’s a big part of the overall appearance and the charm of these vintage watches, especially when the lume has changed into that attractive vintage yellow/brown color. The presence of Radium does not mean that adverse health effects are occurring or could occur. What you might not have realized is that you’re exposed to the same level of radiation when you’re wearing the watch because gamma radiation requires a massive shield (a thick layer of lead, for example) to be absorbed. It's no wonder the girls painting watch dials and such weren't aware of the dangers of straight up eating radium. Thanks for the comment, Sam. That means that the old radium on your watch dial and in the hands doesn’t glow anymore, but it’s still radioactive. Only a small portion of ingested radium is absorbed from the digestive tract and distributed throughout the body. Also, the natural decay of both elements into … I’ve read Kate Moore’s book. Thank you for the very informative article. In 2009 I bought a 100% factory accurate fully restored 1961 (M1) Bulova Accutron Spaceview Alpha 14kt solid white gold from a reputable dealer. It is generally conceded by most reasonable (and hell, probably some unreasonable) individuals, that radiation in excess, like anything else, can do more harm than good. I guess I could buy a geiger counter but I was hoping someone might know the answer to this question. That’s why the use of radium was discontinued in the 1960s. The rest is passed unchanged from the body. At the beginning of the 20th century, Radium was thought to have beneficial health properties and was often added to consumer products such as toothpaste, hair creams, and even food. It undergoes alpha decay, which is radioactive decay by the release of an alpha particle from a nucleus. They had no idea that it was potentially dangerous. As you can see, radium isn’t completely safe. Everybody knows what a dental Xray is so thank you for clarifying. Eventually, safer options were discovered, and the use of radium was discontinued in the 1960s. First of all, though many know what a dental x-ray is, they have little or no clear understanding of negative effects from the dose of radiation, nor do they realize that there is a massive difference between the various types of x-rays. With such a large and extensive network, the roots filter water and nutrients from more soil than your average tree (1).Th… Radium is luminescent, corrodes in water to form radium hydroxide. Well, it’s not an immediate concern, but it’s not safe. Uses of Radium Ra 223 Dichloride: It is used to treat prostate cancer. So, how much ionizing radiation would you expect to be dosed with if you wear a watch with old radium lume? It is equivalent to a dental Xray every hour. As far as I know, it uses the BGW9 SuperLuminova lume so it’s not radium. Because it is so dangerous, only a few ounces are produced each year. Its extremely high levels of radioactivity make it a dangerous health concern. This particular radioisotope is the fifth radioactive descendant of uranium 238, which in turn transforms into a radioactive noble gas, radon 222, with a half-life of 3.8 days. They do release a large amount of beta radiation and most can give off over 100uSv/h when they dont have the crystal over it. I am not so worried about the gamma radiation as the risk of having inhaled a radium particle. These particles have such a large mass that they can only travel for a few centimeters, and they’re quickly absorbed. I have a 1946 telechron telalarm jr. alarm clock with radium hands that i use as my normal alarm clock, is that safe? The gaseous decay product of radium is radon. Is Radium Dangerous in Drinking Water? Everyone is exposed to low levels of Radium because it occurs naturally in the environment. Omega Ranchero. All harmful radiation from watches is gamma radiation because the alpha particles can’t penetrate the crystal and the case. They pointed their brushes on their lips to create a fine tip for the delicate work. In fact, one test for radium contamination is to check a person's exhaled breath and see if it has radon gas in it; if it does, that person must have radium in his or her body. Most of these other elements will decay faster than radium-226, so they may be less dangerous now. That was just what I was wondering, seeing that you mentioned that gamma can pass through skin but never said whether that would be harmful. Do you know if it’s really made out of radium or is it a like-radium lume to make the whole more vintage? If you are experiencing any symptoms or have medical care questions, you should consult your health care provider. Radium is a radioactive element that is extremely dangerous when not handled appropriately. What would be a proper way to safely dispose of it? My father was a watchmaker. Safe for what? That means you’ll have been exposed to approx. It is present in soil, water, rocks, coal, plants, and even food. This is almost exclusively the gamma radiation because the alpha particles will have been blocked. Mass.gov® is a registered service mark of the Commonwealth of Massachusetts. And how do you dispose of the radium? It was used in the production of several products including toothpaste and wristwatches and was thought to be curative until researchers discovered that intense radioactivity had adverse effects on … She got herself unpleasant burns by improperly handling radium, after which the couple knew that their discovery was dangerous. Almost all of the workers were women, and they were told that the paint was harmless. Nice article. The watch crystal and the watch case(back) absorb all the alpha particles while wearing the watch. Read the book “The Radium Girls” and learn that radium is more dangerous than this article claims. If you are concerned about a particular watch, you should have it … A mixture of radium and beryllium will emit neutrons and is used as a neutron source. Radium was also used until the early 1970s in ”glow-in-the-dark” paints, e.g., for dials on clocks, and in other industrial applications such as instrument calibration. The most important thing is that they’re equipped to dispose of radioactive waste. As children, my sister and I were always fascinated with how it glowed intently when we held the radium container under light. You should still be really careful when handling radium watches that does not have any crystal on them. It is important to note that radon, a byproduct of Radium, can be present in buildings, particularly in basements. Let me know in the comments below. The maximum amount of radium the body can take is 0.1 micrograms. Although is the heaviest member of the alkaline-earth group it is the most volatile. There’s a very low level of alpha particle emission from the uranium. Radium can enter the body when it is inhaled or swallowed, and in rare cases through emitted radiation. I do not personally know the exact dose of the radiation received by the wearer, I can safely say that there is likely a much better way of assessing the safety of it then saying it’s like dental x-rays. In general, the greater the total amount of your exposure to radiation from Radium, the more likely you are to develop an adverse health effect. Are they safe? When radium was discovered in the early 1900s, people were fascinated by its mysterious glow and it was added to many everyday products, including paints. Not a single factory worker got sick after they started wearing protective gear and stopped licking their paintbrush. He's also a big fan of science fiction, baseball, and comics. Do you think that it wold pose a real threat to my health if I wanted it to be my daily driver? Always be careful, use protective clothing, and use common sense. Yes, Bulova did use radium. It’s said to use “old radium” as lume. If you really want to be sure, you’ll need to test it with a Geiger counter. I don’t know when they stopped using it. I collect tissues and cloths with old radium in a tin and I take it to the recycling point. Omega stopped using it around 1963. 529 Main St., Suite 1M2A, Charlestown, MA 02129. The alpha particle is a helium-4 nucleus, and it can do a … Unlike alpha radiation, this type of radiation won’t be stopped by paper or plastic and it also penetrates the skin.” So is gamma radiation to be avoided? It has been a concern of mine for quite some time particularly since I have to open the back of the watch to replace the battery from time to time. If I let some watchmaker to clean the hands from radium will the watch be secured from gamma and radon? In other words, it’s a severe health hazard. Tests have shown that a radium dial emits approx. The luminous hands were advertised as new old stock . Radium is a radioactive chemical element, very dangerous, an alpha radiations emitter; radium is also a source of radon, by decay - radon (a gas) is also a radioactive and dangerous element. The amount of radon monitored was even greater among those watches kept in poor condition. His favorite hobby is to pull watches to bits. When radium was first discovered it had a number of uses. Most people are not aware how much 10 uSv/h is. I always collect it to bring it to the recycling center. I own a lot of radium clocks and watches and one of the watches gives off 67uSv with the crystal on and another clock that I have does not have any crystal over it and it gives off 2130uSv! If you suspect that radon might have built up over time, carefully remove the crystal in a well-ventilated room and let it cool down for a while. Radium is an extremely rare element on Earth. Hi, In the early 1900s, the dials and … Better call them first. While that’s not entirely safe, it’s also not an immediate cause for concern. Forgive me if I’m mistaken, but I got the impression that despite gamma radiation’s ability to penetrate paper, plastic, and skin, you think it’s safer than alpha radiation. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. 1. Decasing, removing the hands and dial, and vice versa shouldn’t take more than 30 minutes. Radium, radioactive chemical element, the heaviest of the alkaline-earth metals of the periodic table. The potential for health effects depends on the amount of radiation a person is exposed to. These paints were used on the dials of clocks and watches to make them glow-in-the-dark. That means that you’ll have been exposed to a full day’s worth of background radiation in about 20 minutes. People thought that it was healthy, and it was included as an ingredient in many products. a day and a half worth of background radiation as a watchmaker. This form only gathers feedback about the website. Some absorbed radium is excreted in urine. When exposed to it, the element causes lymphoma, bone cancer, leukemia, and aplastic anemia. We will use this information to improve the site. Or radium and radioactive strontium which collects in the bones. I have been observing a watch that I want to purchase that gives me sleepless nights. That’s why those poor radium girls got sick. Watchmakers discovered that they could mix the radium with paint to create a paint that glows in the dark. Radioactivity was new and exciting. The Radiumscope, a toy sold as late as 1942, offered a glimpse of radium in … Radium is a chemical element with the symbol Ra and atomic number 88. It readily oxidizes on exposure to air, turning from almost pure white to black. Exposure to Uranium and Radium over time can result in dangerous and harmful health effects. At the beginning of the 20th century, Radium was thought to have beneficial health properties and was often added to consumer products such as toothpaste, hair creams, and even food. Number of natural isotopes (atoms of the same eleme… 3% of the radiation is the penetrating gamma radiation. However, radon could only pose a threat in watches that are airtight, like divers. This page, Health effects of Radium radiation exposure, is, Call Radiation Control Program, Main number at, Call Radiation Control Program, RCP emergency number at, in the scale of 1, Strongly Disagree, to 5, Strongly Agree, Professional Training & Career Development, Downloadable version of FAQs: Health Effects of Radium Radiation Exposure (PDF). It doesn’t. It is well known today that radium is a very dangerous substance, only a minute amount of deposited radium in the human body—as little as a microgram (i.e. The seller claims that it was produced back in 1990s. A small amount will enter the blood stream and will be carried to all parts of the body. They had no idea that it was potentially dangerous. Radium in water may pose a hazard to human health when the water is used for drinking or cooking. Those products even included drinks and creams. Side note, somewhere a friend has some neon made from uranium glass. How dangerous was that exposure? Or plutonium dust if inhaled, very bad news. I’ll only wear it from time to time. Unlike alpha radiation, this type of radiation won’t be stopped by paper or plastic, and it also penetrates the skin. The use of radium was discontinued since the 1960s. The particles also can’t penetrate the epidermis, so the skin absorbs them without entering the body. Watchmakers discovered that they could mix the radium with paint to create a paint that glows in the dark. If you would like to continue helping us improve Mass.gov, join our user panel to test new features for the site. Radium had been used to make self-luminous paints for watches, aircraft instrument dials and other instrumentation, but has largely been replaced by cobalt-60, a less dangerous radioactive source. The biggest risk is inhalation or ingestion of radium because alpha particles are harmful inside the body. Several of the women got seriously ill and sued their employer for having contracted an occupational disease. Radium is a silvery white metal that does not occur free in nature. It depends on the watch and how long you wear it. What do you think of those old radium dials and hands? Pierre and Marie Curie discovered radium in 1898 while conducting research with uranium ore. Ra-226 is produced by the radioactive decay of uranium-238. one ten-thousandth of a milligram)—can prove dangerous and even fatal [14]. Radium is silvery, lustrous, soft, intensely radioactive. Would you like to provide additional feedback to help improve Mass.gov? I can’t answer that question. These women are known as the Radium Girls. It’s kinda weird … Let’s address the elephant in the room… are they radioactive? If you’re removing the old lume from the dial or reluming the hands, alpha particles can still be very dangerous if you inhale or ingest some if it. The watch is an original and has already lost its lume in the hannds. Radium has a half-life of 1600 years. Hi, Radium was even used in medical applications during the 20th century. Recently I came across the little tin with a small a out of radium left in it. Secondly, when dose estimates are given for x-ray procedures, they are estimating the actual dose the patient receives, not the amount of radiation emitted from the source. Radium is one type of radioactive material that could be found in antiques. Maby some still there but it will be so low radiation and radon so its safe? White. It’s not safe, that’s why it was banned. But there’s no need to get hysterical about it. It isn’t dangerous. It’ll be more of a threat than a watch without any radioactive material. I don’t know. Its most characteristic property is its intense radioactivity, which causes compounds of the element to display a faint bluish glow in the dark. Many years ago, in efforts to increase technology and make our lives a little bit easier, radium was discovered to create self illuminating clock faces and gadgets. Do you have any tips to remove the paint from dials without destroying the paint? Even family members (in one case a sister who shared a bed with her dial painter sibling) became ill. READ THE BOOK AND LEARN THE TRUTH. Also, does anyone know if a glass jar full of radioactive watches that probably hadn’t been opened in decades, would have created enough radon gas to be seriously dangerous to us. People thought that it was healthy, and it was included as an ingredient in many products. It is produced as a byproduct of uranium mining. The case was settled in 1928, and since that time, radium dial painters were provided with protective gear. Density: 3.2 ounces per cubic inch (5.5 grams per cubic cm) 5. In Radium that is swallowed in water or with food, most of it will promptly leave the body in the feces. Hi, I think that the watch will be safe to wear afterward. According to the United States Environmental Protection Agency, radon is the number one cause of lung cancer among non-smokers. It also comes from natural sources and occurs as background radiation. But if I had to, I’d use a toothpick or cotton swab with some alcohol. Phase at room temperature: solid 6. Melting point: 1,292 degrees Fahrenheit (700 degrees Celsius) 7. Where does it say that gamma radiation is safer than alpha radiation? I can spend about 500€. Over enough time and exposure, Uranium and Radium can lead to increased risk of cancer and organ failure. I actually disagree with the usefulness of the above comparison. The Dutch founder & editor of WahaWatches. AS ALWAYS, BIG BUSINESS ONLY CARES ABOUT PROFITS, NOT PEOPLE. The potential for health effects depends on several factors including the amount of Radium present, amount of time spent near contamination, proximity to the source of radiation, and whether any shielding (e.g., concrete or lead that blocks radiation) is in place. Pure radium is silvery-white, but it readily reacts with nitrogen on exposure to air, forming a black surface layer of radium nitride. https://wahawatches.com/wp-content/uploads/2020/06/new_logo2.png, https://wahawatches.com/wp-content/uploads/2017/11/Radioactive-watches.jpg, All You Need to Know About Waterproof Watches, Service: Onsa Dress Watch With an FHF 72 Movement, Best Watchmaker Screwdrivers for Beginners, Book Review: The Vintage Rolex Field Manual by Colin A. In 1898, Pierre and Marie Curie discovered radium when they found out that the mineral uraninite was still radioactive after they’d removed the uranium. This glow-in-the-dark paint was also … You may be exposed to higher levels of Radium if you work in a specific job using these materials.Â. The information is important for you because radium may cause harmful health effects and because these sites are potential or actual sources of human exposure to radium. I’m presuming it would be. If someone really wants to know, a Geiger counter would be the best way of measuring it. I bought a Steinhart watch one month ago (black military 42 model). Atomic number (number of protons in the nucleus): 88 2. Radon, a byproduct of Radium, can also be measured in air that is exhaled from the body.  Both types of tests require special equipment and cannot be done by most medical offices. However, all over the internet are scary stories about radium, radioactivity, and potential dangers. In your article you say “gamma radiation. It’s still potentially hazardous like you said. Radioactive decay occurs because certain atoms are unstable and need to release energy in an attempt to become stable. Your feedback will not receive a response. 10uSv / hr. Now, we all know that radium dials are a feature of vintage watch and clock collecting. Radium Hot Springs, informally and commonly called Radium, is a village of 776 residents situated in the East Kootenay region of British Columbia.The village is named for the hot springs located in the nearby Kootenay National Park.From Banff, Alberta, it is accessible via Highway 93.. It should be whitish in daylight with a blue glow in the dark. Thank you for this article. Hi, thanks. After testing 30 watches kept in a typical room, researchers discovered that collectively they emitted radon, a radioactive element that is the decay product of radium, in concentrations 134 times greater than the United Kingdom’s recommended safe level. Boiling point: 2,084 F (1,140 C) 8. So, it’s not only the watchmaker who’s affected by the gamma rays but also the wearer. Some tests can be used to help determine if an individual has ever ingested Radium, or determine the total amount of radioactivity in the body. Also, depending on how the paint was mixed up, some dials were very hot, while others were not. Radium is a naturally occurring radioactive metal. Is there a specific type of recycling center I should look for? Those products even included drinks and creams. How was Radium commonly used? In Toys and Nightlights. This is not a myth, it’s true.Their radium levels can be up to 1,000 times higher than what you will find in other foods. High levels of Radium are typically found in waste from former Radium processing and manufacturing facilities, or at former manufacturing facilities that used Radium and have been improperly cleaned. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas. Or is other parts of the watch contemitated?Or have you tested what the diffrent will be? Talk with the doctor. It emits two types of radiation; alpha radiation and gamma radiation. T here is no medical test that can tell you how much Radium you were exposed to, or predict whether you will develop harmful health effects. Glow-in-the-dark paint is now made without radioactive material, but in the early 1900s radioactive materials were used to make paint that glowed. Is Tritium in a watch safe to wear? I remember watching him apply new radium to watch hands. The majority of radon exposures in buildings are from radon coming up from the ground. We have one nearby for the municipality. Do you have any experience with these watches to know if Bulova was still using Radium in 1961? What do people recommend..? I’d replace it with a modern one. This is not caused by pollution or elevated levels of radium in the soil, but rather the very elaborate root system of the Brazil nut tree. Radium dust or gas breathed into the lungs may remain there for months, but it will gradually enter the blood stream and will be carried to all parts of the body, with a portion accumulating in the bones. What about a Tritium dial watches? Thanks, Sebastian. If you have health questions about exposure to Radium you can contact the Environmental Toxicology Program at the Massachusetts Department of Public Health (617) 624-5757. 97% of the radiation is alpha radiation, also known as alpha particles. For example, a standard chest X-ray has approximately 20 times the radiation dose of a dental x-ray. Atomic symbol (on the periodic table of elements): Ra 3. Are you sure it’s radium? Many of the older dress watches are barely dustproof, so there’s no way that gas could have built up. I have an 60s omega seamaster with what i guess is radium on the hands, nothing on the dail. It is found in uranium ores. So, with that stated. Is radium lume that dangerous, or is it a tempest in a teapot? Long-term exposure to radium in drinking water may lead to kidney problems, birth defects, and cancer. Immediately after, substances like promethium and tritium were used as a luminous material, and they’re still being used today. Top-requested sites to log in to services provided by the state, Radium is a radioactive substance found in nature that can have adverse health effects under certain conditions.Â. Book Review: “100+ No BS Watch Tips” by Anthony L. In 1898, Pierre and Marie Curie discovered radiumwhen they found out that the mineral uraninite was still radioactive after they’d removed the uranium. I want to buy my first radium vintage watch. Exposure to Radium over a period of many years may result in an increased risk of some types of cancer, particularly lung and bone cancer. Probably around the early/mid-sixties, just like Omega.
