Check- and reference sources

 

Dose calibrator checking sources are designed to perform periodic calibration checks on radionuclide calibrators to demonstrate the measurement stability of the equipment. The QC-tests may be required by national or state regulations.

Construction
The active material is homogeneously incorporated in approximately 10ml resin in a 25ml plastic vial. The active layer is colour coded by nuclide and is covered by inactive resin. The source is supplied in a lead container.

Tube sources are used either for energy calibration of gamma counters (uncalibrated) or for detector efficiency calibration (calibrated). Calibrated sources are supplied with a certificate of the German Calibration Service (DKD) and are traceable to international standards.

Construction

The nuclide is homogeneously incorporated in 1ml resin in a plastic tube. The empty volume is filled with inactive plastic. For easy identification of the radionuclide the active volume is colour coded.
