Radioactivity induced in gamma-ray spectrometers

A review is given of the data and methods used in the prediction of radioactivity induced in spaceborne gamma‐ray spectrometers by the space radiation environment. The large masses of current and future detectors requires the application of particle transport codes and results from such codes are presented for scintillator detectors. Calculations and irradiation data are also presented for germanium and bismuth germanate and future requirements are outlined.
