Abstract
A radiation sensing unit for a radiation detection system can include a scintillator and a photosensor optically coupled to the scintillator. In an embodiment, the radiation detection system may provide an output signal to a particular radiation flux that is substantially temperature independent over a normal operating temperature range for the scintillator. The radiation sensing unit may further include a controllable radiation source configured to emit radiation and another photosensor coupled to controllable radiation source. A radiation detection system can include a radiation sensing unit and a control module that is coupled to the controllable radiation source and the photosensors. The control module may control the controllable radiation source and control a power supply coupled to the second photosensor in response to signals from the photosensors. In another aspect, a dynode tap from a photomultiplier tube can be used during calibration. Methods of using the foregoing are disclosed.
