News and Comments

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:

  1. 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 inch.
  2. 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 container.
  3. 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.
  4. The dose of radon from your small specimens is not much more than is generated by granite kitchen counters in a standard home.
  5. 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.
  6. 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 beta radiation.

Customer Comments:

"We received from you a specimen of Pyromorphite from Phoenixville. It has got to be the most magnificent specimen of this species we have ever seen. The photos on your website did not do it justice." M. Martin in UK.

"Some months ago, we asked if you could obtain for us a specimen of Fluorite from Illinois. We left you to it knowing that sooner or later you would come up with the goods. And you certainly have. It is an absolute magnificent Fluorite and we can't thank you enough for going to all that trouble to obtain it for us." Marie...

"Thank you John! I just added two nice Diamonds from the North Cape Province, South Africa to my collection. John's service is impeccable! My new prized specimens were described honestly and photographed perfectly. I am a very happy collector! For everyone seeking to buy collection grade (or jewelry grade) Diamonds, John Betts fine minerals in New York is the place to go!" Michael P.
