Radioactive Isotope Sources (International)


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.

You may require a license and/or an import permit to clear customs; we strongly recommend that you find out if one is necessary. Returns are not accepted on any radioactive sources and no refunds are given. Orders shipping to Canada must be shipped by FedEx only.

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

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.

These radioactive sources are dropped shipped from separate location.

*Some source set changes are made dependent on whether you live in an EU or UN Country*
* All Radioisotope & Uranium Ore International orders are shipped via EMS. Except orders going to Canada, which are shipped FedEx Economy. Call or email for pricing. *Shipping Prices are for ground shipments only. Call or email for all other services.

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 0.25 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.
