Does it glow in the dark?
Do
you glow in the dark?
Haha! Nah it's just a curio! I eat me carrots, I'll be fine! I can't imagine it would have housed any Gamma emitters (the most dangerous kind) probably alpha or beta emitters, with short half lives. You've got me paranoid now!
Radium (Ra-226) or Promethium (Pm-147),n was used until the middle of the 90ties fur watch dials and avionics displays. Radium was (and still is) quite a fierce beta emitter with a half life of 12.3 years. But even full force on your wrist, you still only being irradiated with 1/100th of your yearly safe dose per year.
Although I'm always a bit suspicious of 'safe dose' when government officials say it.
Apparently those most at risk are people living in old stone built houses on top of inactive coal fields. Radioactive Radon gas is pretty awful stuff.
The instability of 222Rn, its most stable isotope, makes radon one of the rarest elements. Radon will be present on Earth for several billion more years despite its short half-life, because it is constantly being produced as a step in the decay chains of 238U and 232Th, both of which are abundant radioactive nuclides with half-lives of at least several billion years.
Radon gas is thought to be the #1 cause of lung cancer in the UK, owing to its abundance and prominence in previous coal mining areas, where it has been 'liberated' from safe rocks.
Still, not to worry. We'll all be burnt to a cinder in ten years time on account of El Trump and Musk's climate denial. Both of whom will likely be on a moon of Saturn by then, living it up in an inflatable megastructure till the last hurrah. B#stards every one.
