Do you have any experience with these watches to know if Bulova was still using Radium in 1961? While that’s not entirely safe, it’s also not an immediate cause for concern. Hi, As far as I know, it uses the BGW9 SuperLuminova lume so it’s not radium. It is equivalent to a dental Xray every hour. 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. Alpha particles are highly dangerous inside the body, though, because it kills and mutates cells. However, all over the internet are scary stories about radium, radioactivity, and potential dangers. Radium has a half-life of 1600 years. And how do you dispose of the radium? It is not known if Radium can be absorbed through your skin. Those products even included drinks and creams. Most of these other elements will decay faster than radium-226, so they may be less dangerous now. What do people recommend..? AS ALWAYS, BIG BUSINESS ONLY CARES ABOUT PROFITS, NOT PEOPLE. Radium is a highly radioactive alkali metal. The use of radium was discontinued since the 1960s. 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. Side note, somewhere a friend has some neon made from uranium glass. In other words, it’s a severe health hazard. What about a Tritium dial watches? 529 Main St., Suite 1M2A, Charlestown, MA 02129.

A small amount will enter the blood stream and will be carried to all parts of the body. Radium has received a reputation of being a very dangerous element. 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. Hi, Most people are not aware how much 10 uSv/h is. Exposure to Uranium and Radium over time can result in dangerous and harmful health effects. I bought a NOS watch by CWC. If you really want to be sure, you’ll need to test it with a Geiger counter. But it’s also not as life-threatening as many claim it to be. Higher doses of Radium have been shown to cause effects on the blood (anemia), eyes (cataracts), teeth (broken teeth), and bones (reduced bone growth). Aged lume has often dried out and turned brittle, so that’s certainly a risk when you want to relume the hands, for example. 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. If someone really wants to know, a Geiger counter would be the best way of measuring it. Mass.gov® is a registered service mark of the Commonwealth of Massachusetts.
