    Abstract

    High sensitivity dosemeters based on Al2O3:C have been prepared and tested for use as beta dosemeters using optically stimulated luminescence (OSL). Two types of sample were prepared and tested, namely unpolished thick, single crystal chips and thin powder layers on aluminium substrates. The samples were used in two OSL readout modes: (a) cw-OSL using a tungsten lamp, and (b) pulsed-OSL using a Nd:YAG laser. Comparisons were made with TL properties, where possible. The samples were irradiated using a variety of sources, including Pm-147, Tl-204, Sr-90-Y-90 and Co-60, and under a variety of cover thicknesses. The response per unit H-p(0.07), normalised to Co-60, is compared for each dosemeter type and discussed within the framework of DOELAP and EU recommended limits.
