TYPE TESTING OF THIN-LAYER HOT-PRESSED TLDS - ENERGY AND ANGULAR RESPONSE FOR PHOTONS

The measurement of the ICRU quantities, the individual dose equivalent penetrating, H(p)(d) and superficial, H(p)(d) should be performed at well specified depths. This requirement leads to the use of thin layer detectors. As is known from the literature, the filter/detector confi guration becomes simple if LiF based thermoluminescent detectors are u sed. Long-term stable, fully annealable at 400-degrees-C and LiF-based thin layer TLDs, manufactured by ENDOS GmbH appear suitable for modem radiation protection dosimetry. The filter/thin layer detector config uration within the dosemeter badge has been optimised with respect to the ICRU requirements. Experimental data are reported on energy and an gular response to photons for a few carefully selected filter combinat ions. A dosemeter badge enabling routine H(s)(0.07) and H(p)(10) measu rements is presented.
