Radioactive Sources
No NRC license required
All our radioactive isotopes are legal to purchase & own by the general public.
Sample radioactive sources for testing the functionality of a geiger counter. Safe, uncalibrated solid sealed sources are fabricated by depositing a license exempt quantity of activity in the well of a 1-inch diameter (25mm) by 1/8-inch thick (3mm) plastic disk. After drying, the well is filled with an epoxy material; sealing the radioactivity 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.
All radioactive source prices include the cost of drop shipment from NRC licensed facility. We do not accept international orders of radioactive material

Cloud Chamber Needle Sources
These sources are used for viewing radioactive particle trails in a cloud chamber.
The S-11 contains one alpha (< 0.1 µCi, Po-210) and one beta (< 0.1 µCi, Sr-90) needle source mounted in stoppers. The activity is deposited on the ends of the needles. Rubber stoppers fit into the ends of plastic test tubes for safe, convenient storage.
Pb-210 Needle Cloud Chamber Source Contains Pb-210 < 0.01 µCi
