READ THE BOOK AND LEARN THE TRUTH. You may be exposed to higher levels of Radium if you work in a specific job using these materials.Â. So, how much ionizing radiation would you expect to be dosed with if you wear a watch with old radium lume? Also, depending on how the paint was mixed up, some dials were very hot, while others were not. Now, we all know that radium dials are a feature of vintage watch and clock collecting. I am not so worried about the gamma radiation as the risk of having inhaled a radium particle. Some absorbed radium is excreted in urine. So, it’s not only the watchmaker who’s affected by the gamma rays but also the wearer. Radium is a silvery white metal that does not occur free in nature. 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? The potential for health effects depends on the amount of radiation a person is exposed to. I want to buy my first radium vintage watch. Thanks for the comment, Sam. In 2009 I bought a 100% factory accurate fully restored 1961 (M1) Bulova Accutron Spaceview Alpha 14kt solid white gold from a reputable dealer. We will use this information to improve the site. In Toys and Nightlights. Watchmakers discovered that they could mix the radium with paint to create a paint that glows in the dark. People thought that it was healthy, and it was included as an ingredient in many products. It readily oxidizes on exposure to air, turning from almost pure white to black. 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. Is Tritium in a watch safe to wear? 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. I collect tissues and cloths with old radium in a tin and I take it to the recycling point. 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. 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. Omega stopped using it around 1963. 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. His favorite hobby is to pull watches to bits. Thereâs a very low level of alpha particle emission from the uranium. 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. But if I had to, I’d use a toothpick or cotton swab with some alcohol. Is there a specific type of recycling center I should look for? Radium is a radioactive element that is extremely dangerous when not handled appropriately. If someone really wants to know, a Geiger counter would be the best way of measuring it. 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. 97% of the radiation is alpha radiation, also known as alpha particles. Traces of radium 226 can be found in uranium ore â of the order of one atom per three million. 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. I actually disagree with the usefulness of the above comparison. Always be careful, use protective clothing, and use common sense. Radium is a highly radioactive alkali metal. 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. 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. Long-term exposure to radium in drinking water may lead to kidney problems, birth defects, and cancer. As far as I know, it uses the BGW9 SuperLuminova lume so it’s not radium. 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. 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. Several of the women got seriously ill and sued their employer for having contracted an occupational disease. When exposed to it, the element causes lymphoma, bone cancer, leukemia, and aplastic anemia. There’s a way to handle it safely with the proper protective clothing and procedures. That means that you’ll have been exposed to a full day’s worth of background radiation in about 20 minutes. And thats not counting the alpha radiation. Thank you for the very informative article. Radium has received a reputation of being a very dangerous element. Would my grandfather’s 1967 Accutron contain radium? It emits two types of radiation; alpha radiation and gamma radiation. Almost all of the workers were women, and they were told that the paint was harmless. Radium occurs throughout Earthâs crust but occurs in unusually high levels in certain locations such as uranium mines and fossil-fuel driven factories. Book Review: “100+ No BS Watch Tips” by Anthony L. This glow-in-the-dark paint was also â¦ In the early 1900s, the dials and â¦ 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. Most of these other elements will decay faster than radium-226, so they may be less dangerous now. 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. It’s said to use “old radium” as lume. 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. Also, the natural decay of both elements into â¦ 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. Hi, Boiling point: 2,084 F (1,140 C) 8. However, all over the internet are scary stories about radium, radioactivity, and potential dangers. Radium in water may pose a hazard to human health when the water is used for drinking or cooking. Radium is an extremely rare element on Earth. And how do you dispose of the radium? I can spend about 500€. Its most characteristic property is its intense radioactivity, which causes compounds of the element to display a faint bluish glow in the dark. You should still be really careful when handling radium watches that does not have any crystal on them. Do not include sensitive information, such as Social Security or bank account numbers. It takes about 7 tons of ore just to produce a single gram of radium. The gaseous decay product of radium is radon. With such a large and extensive network, the roots filter water and nutrients from more soil than your average tree (1).Thâ¦ 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 is not known if Radium can be absorbed through your skin. Radium is a naturally occurring radioactive metal. one ten-thousandth of a milligram)âcan prove dangerous and even fatal .

However, every watch is unique so you’ll need to test that particular watch. The use of radium was discontinued since the 1960s. Would you like to provide additional feedback to help improve Mass.gov? Many vintage watches have radium lume on the dial and in the watch hands. Thanks, Sebastian. It’ll be more of a threat than a watch without any radioactive material. 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. The biggest risk is inhalation or ingestion of radium because alpha particles are harmful inside the body. These women are known as the Radium Girls. It doesn’t. It is produced as a byproduct of uranium mining.

It is found in uranium ores. Its extremely high levels of radioactivity make it a dangerous health concern. Radium is a chemical element with the symbol Ra and atomic number 88. Those products even included drinks and creams. It’s not safe, that’s why it was banned. Or is other parts of the watch contemitated?Or have you tested what the diffrent will be? Omega Ranchero. Radioactivity was new and exciting. It should be whitish in daylight with a blue glow in the dark. Better call them first. The case was settled in 1928, and since that time, radium dial painters were provided with protective gear. 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. 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. They had no idea that it was potentially dangerous. In the early 1900s, the dials and hands of nearly all timepieces were painted with this radioluminescent paint. As you can see, radium isn’t completely safe. It is present in soil, water, rocks, coal, plants, and even food. 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. Everyone is exposed to low levels of Radium because it occurs naturally in the environment. Radium has a half-life of 1600 years. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. They licked their brushes with luminous paint hundreds of times a day and ingested radium every time they did so. It's no wonder the girls painting watch dials and such weren't aware of the dangers of straight up eating radium. Read the book “The Radium Girls” and learn that radium is more dangerous than this article claims. However, radon could only pose a threat in watches that are airtight, like divers. Unlike other chemical elements, radium is unnecessary for living organisms and may cause various health effects to the exposed individual. Or plutonium dust if inhaled, very bad news.
