1. A method for calibrating a gamma ray detector, comprising:
- receiving information corresponding to gamma ray energies collected by the detector from background radiation;
analyzing the information to determine if black-listed properties are present, and if one or more black-listed properties are present, disregarding some or all the information;
comparing an energy spectrum associated with the information with one or more spectral features associated with the background radiation; and
calibrating the detector in accordance with the comparing.

Abstract
Characterization, calibration and gain stabilization of gamma ray detectors are carried out using one or more spectral features that are present in the background radiation. Such a spectral feature may be the spectral peak associated with Potassium-40 nuclide. The disclosed methods, apparatus and computer program products enable uninterrupted operation of gamma ray detection systems, while eliminating the costs associated with the procurement and integration of external reference sources into these systems, and without compromising the sensitivity of the detection system.
