Development of a Multi-Sensitive Element Passive Dosemeter Based on OSL Technology

: In 2012 the IEC 62387-1:2007 (IEC.Radiation protection instrumentation-Passive integrating dosimetry systems for environmental and personal monitoring Part 1: General characteristics and performance requirements. IEC 62387-1:2007 (2007)) standard has been transposed by the CENELEC into a European version (EN 62387-1:2012 (Instrumentation pour la radioprotection-Systemes dosimetriques integres passifs pour la surveillance de l'environnement et de l'individu-Partie 1 : Caracteristiques generales et exigences de fonctionnement. NF EN 62387-1:2012 (2012))). In order to meet with this standard, LANDAUER has developed, by Monte-Carlo method, a new dosemeter based on the Optically Stimulated Luminescence technology with Al2O3:C crystals and a new type of dose estimation algorithm. This dosemeter aims at measuring dose equivalent generated from exposure to X-rays, γ-rays and β-rays. According to the standard, it has undergone a comprehensive set of tests that have been performed by the LNE-LNHB, the French national metrology laboratory responsible for the fields of ionizing radiation (Bordy, J.-M. Evaluation of the algorithms used to derive the dose from the raw readings of the Inlight LDR holder case type GN of Landauer. LNHB technical note, LNHB 2013-46 (2013)). In the end, the dosemeter was declared compliant with the EN 62387-1:2012 standard.
