Abstract
Recently there have been some developments in electronic dosemeters for photons using pindiodes to estimate the dose rate. For the evaluation of the fesibility of active dosimetry and the assessment of the suitabilty of existing methods and further developments, it is neccesary to a model the response of the sensor by applying appropriate simulation codes. Computer models have been applied to simulate the pulse high distribution (energy response)for photon irradiations of these pin-diodes. It was found that only low energy photons can be registered within the active layer of the detectors itself due to escape of higher energy quanta out of the active layer. Hence, the thickest possible pin diodes were used for irradiation experiments to achieve as much energy information as possible. Good agreement between experimental data and model calculations for narrow spectra x-ray irradiations and standard radionuclides was found. The important interaction regimes (Photo effect and Compton scattering) are interpreted correctly.
