Radioactive Isotope Sources (International)


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

The 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. For sources requiring shielding, an LSD1 is automatically added to the shopping cart. We will contact you, if a larger shield is more beneficial based on your total order. Images of the LSD1, LSD4, LSD5 are provided at the bottom of page for reference.

All Radioactive Sources are shipped by EMS. Orders shipping to Canada must be shipped by FedEx only. Please email us other inquiries.

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

PRIOR APPROVAL REQUIREMENT:

Different countries have varying regulations, and some may require prior approval to import our radioactive sources. Before we can ship, we need the following documents from the customer: a completed Authorization to Import by Purchaser and if required, copy of the import license/permit from the end-user's country.

Failure to provide these documents may result in additional shipping and storage costs, which will be the responsibility of the customer.

In addition to the form above, the form below is also a requirement for any international customers.

END-USER SCREENING REQUIREMENT:

For all end-users with foreign "Ship-To" addresses, we are required to cross-check their information with the "Consolidated Screening List" available via the BIS website. This is to ensure that the customer/end-user is not:

- Located in a restricted country (i.e., on the Nonproliferation Sanction List).

- Listed on the Denied Persons List.

- Debarred and not allowed to order defense articles.

- On the Specially Designated Nationals List.

To proceed with shipping, we need the following document completed: Form BIS-711, Statement by Ultimate Consignee and Purchaser.


  • International regulations control the isotope and activity that can be exported and shipped internationally.
Below is a list of Images Scientific Instruments standard Sources and Activities.
These Sources and Activities can be exported and shipped internationally.
We have also provided the maximum activity that can be shipped internationally.
Please be aware of your country's regulations before placing your order.
If your country permits users to receive higher activity sources, you must notify us at time of order.

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.

*Changes may be made to activity level of some sources dependent upon on whether you live in an EU or UN Country*

* All Radioisotopes International orders are shipped via EMS. Orders going to Canada are shipped FedEx Economy. Call or email for all other services.

RSS2 EU

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. 		S-6 Source Set
