Obviously someone suffering from being programmed by years of
Superman/Kryptonite disinformation. Gotta watch out for that Marvel
Comics, they are just one more commie front.... Firstly, not all
radiation is the same. Long half lives typically indicate that the
isotopes involved are very stable and emit a very low level of
radiation. Secondly, having a small piece of low radiation material
(like, say, a piece of uranium ore, depleted uranium, or irradiated
glass) is markedly different from handling enriched fissile materials,
or even from living in a location where all the landscape has a low
level of residual radioactivity. Living at Trinity is bad for you, but
visiting there, or taking home a small piece of trinitite, is not
Glass is also much more stable than, say, a piece of radioactive dust.
You inhale far more radioactive isotopes each day from coal plant and
diesel fueled vehicle emissions into the urban atmosphere. Coal plants
sell their fly ash for filler to cement manufacturers for filler,
despite being so laden with radioactive heavy metal isotopes that it
would be high level nuclear was if it was produced by a nuclear plant.
This is the true source of most residential radon contamintion, not
natural emissions from granite rock formations.

A crater, a lump of radioactive rock and soil, and if near a water
table, leaching death....

Could be. I don't think you'd want a loved one wearing it around her
neck. She might need a thyroid transplant a few decades hence, at least
for those from a recent blast.

That is a pretty good guess. I doubt, though, that a blast would
produce very large gems. Large carat gemstones require a significant
amount of constant pressure for a long term to grow without massive
flaws and detectable spectral differences. A blast produces a very
short period of pressure. Even then, most of the crystals that it
produces would be glass/quartz of little value.
