This metal is found in tiny quantities in the uranium ore pitchblende, and various other uranium minerals. The heaviest of the alkaline earth metals, radium is intensely radioactive and resembles barium in its chemical behavior. Its most stable isotope, 226Ra, has a half-life of 1602 years and decays into radon gas. Radium is an alkaline earth metal that is found in trace amounts in uranium ores. Its appearance is almost pure white, but it readily oxidizes on exposure to air, turning black. Seems pretty massive to me, although I don't know what they mean by high ventialtion.Radium ( pronounced /ˈreɪdiəm/) is a radioactive chemical element which has the symbol Ra and atomic number 88. It is significant that the average concentration in this continuously actively ventilated room rose from negligible to over 200 Bq m-3, peaking at over 3000 Bq m-3 when the air circulation systems operated at reduced rates." "Our tests for radon demonstrate that a collection of watches with radium based paint can raise radon concentrations in a room where no radon was previously recorded. "As described above, conservative and precautionary measurements of radon arising from a notional collection of 15 pocket watches, 18 wrist watches and a couple of miscellaneous items indicate that radon concentrations routinely exceed the UK HPA/NRPB Domestic Action Level of 200 Bq m-3 under conditions of high ventilation, rising to over 10 times that Action Level at lower ventilation rates." you are 4 times more likely to die in a car crash. They die from many things.Smoking + Radon is bad.Īnd. If you are a miner, you have a real chance of death form lung cancer from radon. Honestly, if you don't sleep on it, eat it, or grind it up and snort it, you will be fine. What does your CDV700 say it reads? Does it peg all of the scales? (50 mR/hr is the highest scale on that meter.) Now hold the detector 3 feet away, what doe sit say? Its like light, the farther away you get, the dimmer it gets. The amount of radium or radon you would need to be exposed to to have detectable changes in your physiology are very large, on the order of many magnitudes more than you will ever see.Ħ. When you exhale it, it is no longer in you.ĥ. Radon is a gas, when you inhale it, it is in you. ![]() If you live in Denver, built on top of granite and a mile a high, you get about 150 milli-rems a year from naturally occurring background exposure.Ĥc. We are all exposed to radon daily, just like solar radiation, or thorium in sand, potassium in your significant other.Ĥb. Radon is naturally occurring (Part of the decay chain of uranium to lead), and comes from the ground, especially after a rain when the water displaces the gas. The more distant you are, and the less time, will significantly reduce your exposure.Ĥa. Don't sleep on it, and you r exposure to it will be limited. Don't grind on it and inhale the dust, and you will be fine.ģ. ![]() Here is the correct technical reference to the risks of radon. So what do you guys think? I'm by no means afraid of radiation, my office is at 45,000 feet, but I just want to get some informed opinions of whether I should look into some options for my 14X20ft man-cave. ![]() There are a thousand clickbait "radiation is evil" mass-hysteria type articles out there, but that one from northhampton is the only thing semi-official I could find regarding radon coming from watches and clocks. I just stumbled across an article that makes me question that though: The wisdom I'd always operated by was that radium is primarily an alpha emitter so the risks should be minimal so long as I don't open anything up. I've got two Lionel CDV700's to verify things are in fact "hot" even though the CDV's just detect beta and gama. I'm a collector of many things, usually WWII related, and as such I've got some radium painted dials from aircraft instruments and watches/clocks. My question is at the end, but for some context:
