Abstract
The dosimetric properties of a portable TLD reader are described. The TLD system named 'Pille' or 'moth' consists of a lightweight battery-operated portable TLD reader and its CaSO4:Dy bulb dosemeters. The reproducibility of the TLD system at constant temperature was found to be better than ±2%, and the mean time between failures exceeded 5 years. The dose range of the system is wide, covering more than 6 orders of magnitude, from 5 µGy to 10 Gy. The energy dependence of the CaSO4:Dy bulb dosemeters is less than ±20% above 100 keV in the energy compensation capsules. Without additional annealing, the bulb dosemeters can be re-used at least 100 times, which is an important aspect during in situ measurements.Keywords
