Dosemeter Configurations for the Measurement of Hs(0.07) and Hp(10) from Photons

The optimisation is discussed of filter/detector configurations of dosemeters for individual monitoring for photons in the energy range from 20 keV to 1.3 MeV. Experimental data are given on energy and angular responses of dosemeters with different combinations of aluminium and plastic filters. LiF...

Description
Summary:The optimisation is discussed of filter/detector configurations of dosemeters for individual monitoring for photons in the energy range from 20 keV to 1.3 MeV. Experimental data are given on energy and angular responses of dosemeters with different combinations of aluminium and plastic filters. LiF TLD-700, LiF:Mg, Cu, P, and Li2B4O7:Mn TL detectors were investigated for the measurement of Hp (10), and graphite-mixed MgB4O7:Dy, LiF and Li2B4O7 were investigated for the measurement of Hs (0.07). Irradiations were made with a 60Co gamma source and ISO qualities of X radiations. The irradiations were made at incident angles of 0 o, 20 o, 40 o and 60 o with the dosemeters mounted on a cubic Perspex phantom.
