Energy compensated solid state gamma dosimeter

An analytical model of the detector response for a p-i-n diode has been developed and tested with monoenergetic isotopic sources. The model was then used to simulate the detector response over a wide range of photon energies. This matrix was used in turn to calculate a pulse-height correction factor. Irradiation of the device in a variable-energy X-ray beam showed that while there are some fundamental limitations, this approach can improve the accuracy of the measurement of the dose delivered to tissue.<>
