Calibrated Test Tube Sources - CANBERRA, Analytical instruments, systems and services for radiation detection and radiation monitoring

Calibrated Test Tube Sources

These sealed test tube sources are manufactured by depositing radiochemical into the tube and evaporating. After drying, the activity is sealed inside the tube with epoxy. A cap is then secured. The test tubes are calibrated with a high purity germanium detector. Calibration certificates are provided.

License exempt in the United States.
International customers must check their local regulations for exemption limits.
