Abstract

Personal dosimetry is the means of monitoring workers under ionizing radiation in Madagascar. This dosimetry consists in measuring the operational quantities Hp (10) or Hp (0.07) (equivalent doses to the whole organism and to the skin) and to check that these values do not exceed the authorized annual dose limit. In fact, dose limitation is one of the means of protecting workers against the harmful effects of ionizing radiation. In Madagascar, the Dosimetry and Radiation Protection Department of INSTN-Madagascar has a HARSHAW 6600 personal dosimeter reader. It is a powerful device because it reads automatically and can read 200 cards at one time. Despite the capacity of this device, there is still some manual work to do for data management, by recording in a "log book" the doses read by the reader and joining them in the database of workers. To address the objective of specifically managing the doses received by workers. The goal of this work is to facilitate the reading process of TLDs by recovering the data coming from the reader and by exploiting them in the database of the workers. With more than a thousand personal passive dosimeters distributed to more than 700 workers under ionizing radiation in Madagascar and abroad. This monitoring has been carried out since 1993 until today. If the dose is exceeded, the employer must specify the presumed causes of the excess and inform the INSTN and the labor inspectorate.
