Radioactive Isotope Sources (International)





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


Note: 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.



Countries requiring prior approval


  1. The following countries require prior approval from the proper agency within their country to receive Radioactive Material from outside the country. Please contact your country's agency and supply Images Scientific Instruments with authorization prior to placing your order. If you need information about your agency it is listed in the ICAO/IATA regulations, section 2.8.2 or contact Images Scientific Instruments and we will forward the information to you.

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.


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.

Uranium Ore Paperweight

Encased Uranium Ore Soil


License exempt - Check Source.
Size Approximately - 1.5" dia. x .125" (1/8") thick
Radioactivity levels vary from disc to disc.
Radioactive soil encased in polyester plastic as shown.

The encased uranium ore soil 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 encase 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.

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.
