No NRC license required!
All our radioactive isotopes are legal to purchase & own by the general public.

To ensure the longest half-life possible, we do NOT keep isotopes in stock.
All isotopes are produced fresh in a Nuclear Reactor and
shipped directly to you from the NRC licensed isotope manufacturer.

- SORRY, NO INTERNATIONAL SALES OF RADIOACTIVE ISOTOPES -
Sorry, we only fill orders within the United States. This policy applies to all of our products, including common items like our T-Shirts & Coffee Mugs.



A SPECIAL NOTICE ABOUT POLONIUM-210

With the recent news of Polonium-210 being used as a poison, a good deal of
incorrect information has been passed around (primarily by the media) concerning the Polonium isotope and radioactive materials in general. It's important to get the facts correct. The general public is quite ignorant when it comes to knowledge about radioactive materials and radiation in general.

The amount of Plonium-210, as well as any of the isotopes we sell is an 'exempt quantity' amount. These quantities of radioactive material are not hazardous - this is why they are permitted by the Nuclear Regulatory Commission (NRC) to be sold to the general public without any sort of license.
Although we do sell these isotopes, distributors such as United Nuclear Scientific Supplies (and just about any isotope distributor) do not actually stock them.
All isotopes are made to order at an NRC licensed reactor in Oak Ridge Tennessee. When the isotope is made, it is shipped directly to the customer from the reactor to insure the longest possible half-life.

The exempt quantity amount of Polonium-210, or any of the radioactive isotopes sold is so small that they are essentially invisible to the human eye.
In the case of needle sources, the radioactive material is electroplated on the inside of the eye of a needle.

You would need about 15,000 of our Polonium-210 needle sources
at a total cost of about $1 million - to have a toxic amount.
