 Radioisotope Sources
The following table presents the standard radioisotope products of Spectrum
Techniques.
Note: For both Domestic and International Source Orders
- Activities of gamma emitters over 5 to 10 uCi MAY
require lead shielding, either LSD1, LSD4 or LSD5.
If required, the lead shield and appropriate price will be added to your order.
If you need a special source, up to the maximum activity limits, as shown below,
just let us know!
