Radioactive Sources (Domestic USA)


Radioactive isotopes are drop-shipped from a different location and can not be returned or refunded.

Shopping cart may not calculate shipping cost for radioactive isotopes correctly. If so, you will be contacted and charged additional shipping costs before order is processed.

For Domestic and international source orders - Activities of gamma emmitters over 5 to 10 μCi MAY require lead shielding, either LSD1, LSD4, or LSD5. If required, the lead shield and appropriate price will be added to your order.

For UPS Next Day, 2nd Day, and 3 Day select please contact us for pricing.

All orders for radioactive materials will be confirmed by a secondary email within 3 business days.



License Free

Radioactive Sources 1


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, and production date (month/year). The words "Caution - Radioactive Material" appear on the label of each source.

Radioactive Source Sets


S-7 Source Set

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.

S-6 Source Set
This set is used for determining the resolving time of GM Counters. It consists of three half discs, two of which contain 5 microcuries of Tl-204 plus a third half disc with no activity. The count-rate of each half disc plus the blank (to maintain constant geometry) is measured and then both active half discs are combined for a measurement with high count-rate. The counting loss may now be calculated by adding the rates from each half disc and comparing the result to the count-rate with both halves combined.

Uranium Ore

Uranium Ore

Useful for testing Geiger Counters.
License exempt.
Uranium ore sample sizes vary.
Shipped in labeled metal container as shown.
Container size approximately 1-3/4" height 2-1/2" diameter.


Each uranium ore specimen is radioactive and measured with a NRC certified GCA-07W Digital Geiger Counter. Activity of alpha, beta and gamma in Counts Per Minute (CPM) is provided along with measurement certification. Uranium 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. CPM is total radiation read from 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.

Size Approximately - 1.0" dia. x .125" (1/8") thick
Radioactivity levels vary from disc to disc.
Radioactive soil encased in polyester plastic as shown.

The uranium ore soil is mixed with a polyester resin and cast into a disc. The disc is radioactive and tested with a NRC certified GCA-07W Digital Geiger Counter. The radioactivity of the embedded uranium ore soil is reduce by being encased in plastic. The low level radioactivity is still perfect for using as a check source for geiger counters. The radioactivity level will vary from disc to disc. This is a non calibrated radioactive check source.
