Safe for what? Melting point: 1,292 degrees Fahrenheit (700 degrees Celsius) 7. Everybody knows what a dental Xray is so thank you for clarifying. Radon, a byproduct of Radium, can also be measured in air that is exhaled from the body.Â Both types of tests require special equipment and cannot be done by most medical offices. It should be whitish in daylight with a blue glow in the dark. 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. 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used to make self-luminous paints for watches, aircraft instrument dials and other instrumentation, but has largely been replaced by cobalt-60, a less dangerous radioactive source. Several of the women got seriously ill and sued their employer for having contracted an occupational disease. The amount of radon monitored was even greater among those watches kept in poor condition. Its extremely high levels of radioactivity make it a dangerous health concern. 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. 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. Radium is a naturally occurring radioactive metal. 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 Kingdomâs recommended safe level. What about a Tritium dial watches? Rings through to Massachusetts State Police. And thats not counting the alpha radiation. Mass.gov® is a registered service mark of the Commonwealth of Massachusetts. Are they safe? Atomic number (number of protons in the nucleus): 88 2. Radium in water may pose a hazard to human health when the water is used for drinking or cooking. They had no idea that it was potentially dangerous. Radium is one type of radioactive material that could be found in antiques. In the early 1900s, the dials and 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. The most important thing is that they’re equipped to dispose of radioactive waste. Read the book “The Radium Girls” and learn that radium is more dangerous than this article claims. Do not include sensitive information, such as Social Security or bank account numbers. Did Bulova use radium in its watches and if so, when was that practice discontinued? It is found in uranium ores. How much do you agree with the following statements in the scale of 1, Strongly Disagree, to 5, Strongly Agree? They pointed their brushes on their lips to create a fine tip for the delicate work. Immediately after, substances like promethium and tritium were used as a luminous material, and they’re still being used today. Plutonium is at the heart of one of the most devastating weapons the world has ever seen â thousands were killed when the atomic bombs were dropped on Hiroshima and Nagasaki during World War II.. Most of these other elements will decay faster than radium-226, so they may be less dangerous now. I have been observing a watch that I want to purchase that gives me sleepless nights. White. It was not only the dial painters that became ill. I collect tissues and cloths with old radium in a tin and I take it to the recycling point. 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! Are you sure it’s radium? In the early 1900s, the dials and hands of nearly all timepieces were painted with this radioluminescent paint. For example, a standard chest X-ray has approximately 20 times the radiation dose of a dental x-ray. Traces of radium 226 can be found in uranium ore â of the order of one atom per three million. 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. A mixture of radium and beryllium will emit neutrons and is used as a neutron source. In Radium that is swallowed in water or with food, most of it will promptly leave the body in the feces. These particles have such a large mass that they can only travel for a few centimeters, and they’re quickly absorbed. 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 not known if Radium can be absorbed through your skin. I don’t know when they stopped using it. Unlike other chemical elements, radium is unnecessary for living organisms and may cause various health effects to the exposed individual. This form only gathers feedback about the website. I want to buy my first radium vintage watch. It doesn’t. Everyone is exposed to low levels of Radium because it occurs naturally in the environment. Well, it’s not an immediate concern, but it’s not safe. If you are experiencing any symptoms or have medical care questions, you should consult your health care provider. Also, depending on how the paint was mixed up, some dials were very hot, while others were not. Talk with the doctor. Many of the older dress watches are barely dustproof, so there’s no way that gas could have built up. Probably around the early/mid-sixties, just like Omega. The particles also can’t penetrate the epidermis, so the skin absorbs them without entering the body. As opposed to radioactive iodine which gets taken up by the thyroid. In your article you say “gamma radiation. All harmful radiation from watches is gamma radiation because the alpha particles can’t penetrate the crystal and the case. I don’t know. Pure radium is silvery-white, but it readily reacts with nitrogen on exposure to air, forming a black surface layer of radium nitride. I’ll only wear it from time to time. Thanks for the comment, Sam. 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. Or radium and radioactive strontium which collects in the bones. Radium is a radioactive substance found in nature that can have adverse health effects under certain conditions. 529 Main St., Suite 1M2A, Charlestown, MA 02129. a day and a half worth of background radiation as a watchmaker. However, all over the internet are scary stories about radium, radioactivity, and potential dangers. I can spend about 500€. Phase at room temperature: solid 6. If you really want to be sure, you’ll need to test it with a Geiger counter. People thought that it was healthy, and it was included as an ingredient in many products. 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. 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. It is equivalent to a dental Xray every hour. You should still be really careful when handling radium watches that does not have any crystal on them. The watch is an original and has already lost its lume in the hannds. 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. 3% of the radiation is the penetrating gamma radiation. 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. As you can see, radium isn’t completely safe. 1. This is almost exclusively the gamma radiation because the alpha particles will have been blocked. But if I had to, I’d use a toothpick or cotton swab with some alcohol. The luminous hands were advertised as new old stock . Many vintage watches have radium lume on the dial and in the watch hands. Also, does anyone know if a glass jar full of radioactive watches that probably hadnât been opened in decades, would have created enough radon gas to be seriously dangerous to us. Now, we all know that radium dials are a feature of vintage watch and clock collecting. 10uSv / hr. Is Tritium in a watch safe to wear? 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. The seller claims that it was produced back in 1990s. Atomic symbol (on the periodic table of elements): Ra 3. The alpha particle is a helium-4 nucleus, and it can do a â¦ 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 readily oxidizes on exposure to air, turning from almost pure white to black. While that’s not entirely safe, it’s also not an immediate cause for concern. Only a small portion of ingested radium is absorbed from the digestive tract and distributed throughout the body. 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. I am not so worried about the gamma radiation as the risk of having inhaled a radium particle. They had no idea that it was potentially dangerous. If you are concerned about a particular watch, you should have it â¦ Decasing, removing the hands and dial, and vice versa shouldn’t take more than 30 minutes. Do you know if it’s really made out of radium or is it a like-radium lume to make the whole more vintage? It undergoes alpha decay, which is radioactive decay by the release of an alpha particle from a nucleus. These paints were used on the dials of clocks and watches to make them glow-in-the-dark. Not a single factory worker got sick after they started wearing protective gear and stopped licking their paintbrush. So, it’s not only the watchmaker who’s affected by the gamma rays but also the wearer. It may be given to you for other reasons. Hi, I have an 60s omega seamaster with what i guess is radium on the hands, nothing on the dail. 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. It emits two types of radiation; alpha radiation and gamma radiation. Radium was also used until the early 1970s in âglow-in-the-darkâ paints, e.g., for dials on clocks, and in other industrial applications such as instrument calibration. I always collect it to bring it to the recycling center. He's also a big fan of science fiction, baseball, and comics. That means you’ll have been exposed to approx. 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. Yes, Bulova did use radium. What would be a proper way to safely dispose of it? You’ll be more exposed because you’ll likely wear a watch for more than 30 minutes at a time. It’ll be more of a threat than a watch without any radioactive material. Also, the natural decay of both elements into â¦ Itâs kinda weird â¦ Radium is luminescent, corrodes in water to form radium hydroxide. Density: 3.2 ounces per cubic inch (5.5 grams per cubic cm) 5. Radium was even used in medical applications during the 20th century. 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. In Toys and Nightlights. The Radiumscope, a toy sold as late as 1942, offered a glimpse of radium in â¦ Uses of Radium Ra 223 Dichloride: It is used to treat prostate cancer. Do you have any experience with these watches to know if Bulova was still using Radium in 1961? It's no wonder the girls painting watch dials and such weren't aware of the dangers of straight up eating radium. In other words, it’s a severe health hazard. 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 do people recommend..? As children, my sister and I were always fascinated with how it glowed intently when we held the radium container under light. If I let some watchmaker to clean the hands from radium will the watch be secured from gamma and radon? 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. When exposed to it, the element causes lymphoma, bone cancer, leukemia, and aplastic anemia. What do you think of those old radium dials and hands? Some of this Radium will then leave the body in a personâs feces and urine on a daily basis and some may remain in the bones throughout the personâs lifetime. 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. Radium is a highly radioactive alkali metal. However, every watch is unique so you’ll need to test that particular watch. Ra-226 is a radioactive substance found in nature. 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. Radium has received a reputation of being a very dangerous element. Atomic weight (average mass of the atom): 226 4. Radioactivity was new and exciting. If you would like to continue helping us improve Mass.gov, join our user panel to test new features for the site. But there’s no need to get hysterical about it. We will use this information to improve the site. 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. Higher doses of Radium have been shown to cause effects on the blood (anemia), eyes (cataracts), teeth (broken teeth), and bones (reduced bone growth). 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). Thank you for this article. I bought a Steinhart watch one month ago (black military 42 model). Omega stopped using radium around 1963. According to the United States Environmental Protection Agency, radon is the number one cause of lung cancer among non-smokers. Over enough time and exposure, Uranium and Radium can lead to increased risk of cancer and organ failure. Those products even included drinks and creams. The majority of radon exposures in buildings are from radon coming up from the ground. Long-term exposure to radium in drinking water may lead to kidney problems, birth defects, and cancer. Its most characteristic property is its intense radioactivity, which causes compounds of the element to display a faint bluish glow in the dark. I have a 1946 telechron telalarm jr. alarm clock with radium hands that i use as my normal alarm clock, is that safe? Is Radium Dangerous in Drinking Water? Nowadays, Super-LumiNova, which is entirely non-radioactive and non-toxic, is the most used lume in watchmaking. It takes about 7 tons of ore just to produce a single gram of radium. Radium is silvery, lustrous, soft, intensely radioactive. Thank you for the very informative article. However, radon could only pose a threat in watches that are airtight, like divers. That means that you’ll have been exposed to a full day’s worth of background radiation in about 20 minutes. How was Radium commonly used? I actually disagree with the usefulness of the above comparison. People thought that it was healthy, and it was included as an ingredient in many products. The gaseous decay product of radium is radon. 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.. Watchmakers discovered that they could mix the radium with paint to create a paint that glows in the dark. Boiling point: 2,084 F (1,140 C) 8. Those products even included drinks and creams. Is there a specific type of recycling center I should look for? I try to keep away from the dial as much as possible because it’s very easy to accidentally remove varnish or lettering/markings. Do you have any tips to remove the paint from dials without destroying the paint? 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. When radium decays, ionizing radiation Aged lume has often dried out and turned brittle, so that’s certainly a risk when you want to relume the hands, for example. It is produced as a byproduct of uranium mining. These women are known as the Radium Girls. Always be careful, use protective clothing, and use common sense. It’s still potentially hazardous like you said. Nice article. Omega Ranchero. There’s a way to handle it safely with the proper protective clothing and procedures. It is important to note that radon, a byproduct of Radium, can be present in buildings, particularly in basements. Or is other parts of the watch contemitated?Or have you tested what the diffrent will be? 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? Hi, I think that the watch will be safe to wear afterward. She got herself unpleasant burns by improperly handling radium, after which the couple knew that their discovery was dangerous. I remember watching him apply new radium to watch hands. 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. Thanks, Sebastian. It depends on the watch and how long you wear it. I bought a NOS watch by CWC. How dangerous was that exposure? The watch crystal and the watch case(back) absorb all the alpha particles while wearing the watch. Low levels of exposure to Radium are normal, and there is no evidence that exposure to low levels is harmful. So, with that stated. I guess I could buy a geiger counter but I was hoping someone might know the answer to this question. Hi, Exposure to Uranium and Radium over time can result in dangerous and harmful health effects. When ingested, radium is particularly dangerous: "Chemically, it behaves very much like calcium," said Jorgensen. Let me know in the comments below. The use of radium was discontinued since the 1960s. Book Review: “100+ No BS Watch Tips” by Anthony L. Maby some still there but it will be so low radiation and radon so its safe? Where does it say that gamma radiation is safer than alpha radiation? 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. Pierre and Marie Curie first identified the radium element in 1898, but it wasnât until 1910 that Marie successfully isolated a sample of it to work with. Every now and again, thereâll be a uranium atom that undergoes spontaneous fission. Radioactivity was new and exciting. Some absorbed radium is excreted in urine. 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. I’m presuming it would be. Radium, radioactive chemical element, the heaviest of the alkaline-earth metals of the periodic table. You may be exposed to higher levels of Radium if you work in a specific job using these materials.Â. Some tests can be used to help determine if an individual hasÂ everÂ ingested Radium, or determine the total amount of radioactivity in the body. Radium has a half-life of 1600 years. 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. 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. I’ve read Kate Moore’s book. AS ALWAYS, BIG BUSINESS ONLY CARES ABOUT PROFITS, NOT PEOPLE. It is present in soil, water, rocks, coal, plants, and even food. Better call them first. It’s said to use “old radium” as lume. My father was a watchmaker. Radium is a silvery white metal that does not occur free in nature. The Dutch founder & editor of WahaWatches. That’s why the use of radium was discontinued in the 1960s. 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. Hi, thanks. It’s not safe, that’s why it was banned. Would my grandfather’s 1967 Accutron contain 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 â¦ 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. Radium occurs throughout Earthâs crust but occurs in unusually high levels in certain locations such as uranium mines and fossil-fuel driven factories. Radium is a radioactive element that is extremely dangerous when not handled appropriately. Or plutonium dust if inhaled, very bad news. Almost all of the workers were women, and they were told that the paint was harmless. Letâs address the elephant in the roomâ¦ are they radioactive? I’d replace it with a modern one. If someone really wants to know, a Geiger counter would be the best way of measuring it. The presence of Radium does not mean that adverse health effects are occurring or could occur. Omega stopped using it around 1963. Most people are not aware how much 10 uSv/h is. 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. And how do you dispose of the radium? Thereâs a very low level of alpha particle emission from the uranium. Alpha particles are highly dangerous inside the body, though, because it kills and mutates cells. This is not a myth, itâs true.Their radium levels can be up to 1,000 times higher than what you will find in other foods. Number of natural isotopes (atoms of the same elemeâ¦ 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. Radium can enter the body when it is inhaled or swallowed, and in rare cases through emitted radiation. Eventually, safer options were discovered, and the use of radium was discontinued in the 1960s. The case was settled in 1928, and since that time, radium dial painters were provided with protective gear. 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. The maximum amount of radium the body can take is 0.1 micrograms. Do you think that it wold pose a real threat to my health if I wanted it to be my daily driver? This glow-in-the-dark paint was also â¦ Radium is an extremely rare element on Earth. With such a large and extensive network, the roots filter water and nutrients from more soil than your average tree (1).Thâ¦ 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. Watchmakers discovered that they could mix the radium with paint to create a paint that glows in the dark. Tests have shown that a radium dial emits approx. Side note, somewhere a friend has some neon made from uranium glass. It is well known today that radium is a very dangerous substance, only a minute amount of deposited radium in the human bodyâas little as a microgram (i.e. Radium is a chemical element with the symbol Ra and atomic number 88. It also comes from natural sources and occurs as background radiation. Your feedback will not receive a response. His favorite hobby is to pull watches to bits. In 1898, Pierre and Marie Curie discovered radiumwhen they found out that the mineral uraninite was still radioactive after theyâd removed the uranium. Yet, at the time, very few scientists or advertisements discussed or even referred to its physical properties. As far as I know, it uses the BGW9 SuperLuminova lume so it’s not radium. It isnât dangerous. That’s why those poor radium girls got sick. 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. That means that the old radium on your watch dial and in the hands doesn’t glow anymore, but it’s still radioactive. I can’t answer that question. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Would you like to provide additional feedback to help improve Mass.gov? Unlike alpha radiation, this type of radiation won’t be stopped by paper or plastic, and it also penetrates the skin. Is radium lume that dangerous, or is it a tempest in a teapot? The potential for health effects depends on the amount of radiation a person is exposed to. But it’s also not as life-threatening as many claim it to be. Although is the heaviest member of the alkaline-earth group it is the most volatile. 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. Recently I came across the little tin with a small a out of radium left in it. 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. 529 Main St., Suite 1M2A, Charlestown, MA 02129 to my health if i let some watchmaker clean!
