Older collectors are often afraid of collecting radioactive minerals because
they lived through the Atomic-bomb era when people were building bomb shelters
in their back yards and the cold war was at it's peak. But collecting radioactive
minerals is possible and safe if you remember these key factors:
Distance is your friend. Radiation exposure falls at the square of the distance.
Therefore the dose received at 4 inches is 1/16th of the dose at 1
Radon gas is generated by decaying radioactive minerals and is the main health
concern. Keeping the radioactive specimens in Tupperware actually concentrates
the radon gas in the container. Be careful not to breathe in as you open
The good news is that radon is heavier than air. If you have a basement in
your home, then it is possible for the radon to accumulate there. Most homes
built where there is granite bedrock have radon expulsion systems that actively
vents accumulated radon to the outside.
The dose of radon from your small specimens is not much more than is generated
by granite kitchen counters in a standard home.
If you had some REALLY HOT specimens like a large torbernite or cuprosklodowskite
then I would advise storing them in your garage where radon gas is dispersed
outside and your distance from them is largest.
Do not ingest radioactive minerals - even accidentally. Breathing in dust
from decomposing specimens or eating food after handling radioactive minerals
is dangerous. Dispose of decomposing specimens (like autunite from the Daybreak
Mine in Washington). Wear disposable gloves (available at any hardware store)
when handling radioactive minerals.
I prefer to mount radioactive minerals in Perky-style display boxes. I handle
them once during mounting, then never touch the mineral again, instead handling
only the display box. The box also has the benefit of blocking alpha and
