PROGRESS IN QUALITY-CONTROL OF ALANINE DOSIMETERS

The ESR/alanine system has been used for different applications, over several years, as a classical routine dosimetry service. This service is based on alanine dosimeters constituted by pellets manufactured by our laboratory, which are presented with some specifications of use an d different parameters bound to the intrinsic quality of the dosimeter itself. These parameters were obtained through the strict application of a production protocol and a validation protocol created, tested an d validated under a quality assurance system. Every year, one batch of photon dosimeters is produced and controlled using these protocols an d the specifications associated with it are checked. Two categories of data are considered separately: physical parameters and experimental data obtained by measurement on our ESR system are given with their as sociated standard deviation.
