Radioactive Sources

License Free


All our radioactive isotopes and sources are legal to purchase and own by the general public.
See
NRC Regulations.


Sample radioactive sources are for testing the functionality of a Geiger counter and for performing experiments involving radioactivity.

These are safe, uncalibrated solid sealed sources. They are fabricated by depositing a license exempt quantity of radioactive material in the well of a 1-inch diameter (25mm) by 1/8-inch thick (3mm) plastic disk. The well is filled with an epoxy sealing the radioactive material inside the source.

Contains ±20% of the stated activity and are routinely compared to calibrated reference standards. Each disk is identified by radio nuclide, amount of activity, serial number and calibration date. The words "Caution - Radioactive Material" appear on the label of each source.

Uranium Ore


Uranium Ore

Radioactive uranium ore sample.


Useful for testing Geiger Counters.
License exempt.
Uranium ore sample sizes vary.
Shipped in labeled metal container as shown.


Each radioactive ore sample is measured with A GCA-04W Digital Geiger Counter. Activity of alpha, beta and gamma in Counts Per Minute (CPM) is provided along with measurement certification. Ore samples typically have one area that is more radioactive than other areas. Measurement of radioactivity is taken from the most radioactive portion of the sample.
