Abstract :
A previous Monte Carlo program, ISIDE, for the simulation of semiconductor gamma ray detectors, has been extended to a new code, PHANTOM, which can be used either for calculating the gamma ray exposure from the output of semiconductor detectors working in pulse mode or for determining the isodose curves in a cylindrical phantom exposed to a disk gamma ray source. The results are used to evaluate the exposure from the spectra recorded by a HgI2 detector in the energy range 10 KeV - 1 MeV. A good agreement with experimental results either for phantoms and for semiconductor detectors is obtained.
