Performance criteria for personal dosemeters have been recently proposed in the CEC document 'Technical Recommendations for Monitoring Individuals Occupationally Exposed to External Radiation' (EUR 5287, Revised). The current experiment was carried out to demonstrate that TLD-based dosimetry systems can comply with these requirements. The emphasis of the experiment was on the dosemeter response as a function of photon energy and angle of incidence of the radiation. The tests were based on the ICRU operational quantities H(p) (0.07) and H(p) (10). All measurements were compared with the true dose in a 30 x 30 x 15 cm tissue-equivalent slab phantom, calculated using appropriate conversion coefficients. For each combination of photon energy and angle, three dosemeters of each system were irradiated simultaneously on a 30 x 30 x 15 cm PMMA phantom. No corrections were made for possible - but unknown! - influence on the dosemeters from the difference in backscatter between tissue-equivalent material and PMMA.
