| description | A direct analytical mathematical method is introduced to calculate the
efficiency of gamma ray cylindrical detectors. The efficiency expression is
deduced through a straightforward mathematical approach. The presented method
is based on the accurate analytical calculation of the average path length
covered by the photon within the detector's active volume, effective solid
angle, and the efficiency transfer method in an integral form, so as to
obtain a simple formula for the detection efficiency. In addition, the
self-attenuation coefficient of the source matrix, the attenuation factors of
the source container (with a radius smaller than the detector radius) and the
detector housing materials are also treated by calculating the average path
length within these materials. 152Eu aqueous radioactive sources covering the
energy range from 121 keV to 1408 keV were used. Remarkable agreement between
the measured and the calculated efficiencies was achieved, with discrepancies
less than 6 %. |
