Tube Sources for Well Crystals
We offer a selection of exempt quantity gamma sources encapsulated in standard size test tubes for use with well type radiation detectors. These sources are uncalibrated and of nominal activity. The isotope is deposited as a point source in the bottom of the tube and is then sealed with epoxy. Standard tube size is 12 x 75 mm. Isotopes may be selected from the following table.
| Nuclide | Minimum Activity | Maximum Activity |
|---|---|---|
| Barium 133 | 0.1 µCi (3.7 kBq) | 10 µCi (370 kBq) |
| Cadmium 109 | 0.1 µCi (3.7 kBq) | 10 µCi (370 kBq) |
| Cesium 137 | 0.05 µCi (1.85 kBq) | 10 µCi (370 kBq) |
