DESCRIPTION OF MODULAR DEVICES FOR THE MEASUREMENT OF EXTERNAL DOSIMETRY IN RADIATION PROTECTION

摘要

In 2002 the Group of Radiation Dosimetry and Calibration of the Belgian Nuclear Research Centre (SCK • CEN) has developed an experimental device based on the optically stimulated luminescence (OSL) working with Al_2O_3:C detectors (TLD-500 and Luxel) stimulated with an argon laser. A set of devices made from different modules have been developed to permit external dosimetry measurements with thermoluminescence (TL) and OSL techniques under different conditions. This study describes these measurement devices that can be made with these modules and some of the characteristics of the different systems. These devices present several advantages in terms of measurement possibilities: a small number of modules allow the use of different detection materials (Al_2O_3:C, BeO, quartz electronic components and tiles) and different measurement methods (TL, CW-OSL and pulsed OSL). Some applications are commented.
