No NRC license required

All our radioactive isotopes are legal to purchase & 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 radioactivite 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.

*Shipping Prices are for ground shipments only. Call or email for all other services.

Several types of source certificates are available for an additional fee. All certificates must be ordered at the same time the source is ordered.

Certificate of Origin: Certifies that the product is manufactured in Oak Ridge Tennessee, Anderson County United States of America.

Certificate of Compliance: Certifies that the source is in compliance with the US NRC and DOT regulationand that the surface has been wipe tested.

Certificate of Calibration: Certifies that the source has been calibrated, list intensity, emission and uncertainty.

These sources are used for viewing radioactive particle trails in a cloud chamber or spinthariscopes.

The needle sources are 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 Lead-210 Needle Source Emits both Alpha and Beta radiation for a variety of experiments. Long half-life of over 20 years.

PO-210 Needle Cloud Chamber Source Contains Polonium-210 (< 0.1 µCi, Po-210) Needle Source Emits strong Alpha radiation (particles) and produces thick condensation trails.

SR-90 Needle Cloud Chamber Source Contains (< 0.1 µCi, Sr-90) Needle Source Emits strong beta radiation.

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.

These radioactive sources are dropped shipped from separate location.

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.

Shipping Information:

We are always in compliance with Section 13 from part 40 of the NRC Nuclear Regulatory Commission rules and regulations and Postal Service regulations specified in 49 CFR 173.421 for activity limits of low level radioactive materials. Item will be shipped in accordance with Postal Service activity limits specified in Publication 52.

Radioactive minerals are for educational and scientific use only.

Sale of uranium ore is in compliance with all U.S. Federal regulations (Part 40) and NY State Regulations (10 NYCRR Part 16 and 12 NYCRR Part 38) as defined under Appendix A exemptions.
