Intrinsic sensitivity calculation for a large number of LiF(Mg, Cu, P) detectors; Determinazione della sensibilita` intrinseca di un numero elevato di dosimetri personali di LiF (Mg, Cu, P)

Abstract

At the ENEA (Italian National Agency for New Technologies, Energy and the Environment) Personal Dosimetry Service it was decided to substitute the X and gamma dosimetry system based on BeO detectors in use since 10 years ago, with new dosimeters based on the new thermoluminescence material LiF(Mg,Cu,P). This report describes the procedures through which intrinsic sensitivity of a couple of TL detectors, which constitutes a card dosemeter, is determined. The intrinsic sensitivity archive allows to calculate the value of dose applying a specific correction factor for the systematic sensitivity, difference among the 60000 detectors used at the Service, therefore reducing the final uncertainty. The characterization of 60000 TL detectors has been possible only relying on a specific procedure and an information system. The irradiation and reading procedure allowed to take into account all the various uncertainty sources on TL readings and to carry out only one reading for almost all detectors. It could get through this aim using a reference group of dosimeters, characterized with an accuracy of 3%, to check each uncertainty parameter. Data acquisition and intrinsic sensitivity calculation have been carried out through an interactive procedure based on a personal computer connected with the reading instrument.
