Abstract
Abstract The relative thermoluminescent response of LiF:Cu,Mg,P to 4 MeV alpha particles has been calculated theoretically using the convolution of the radial dose around the alpha particle track with the gamma generated TL dose response function, with the result ?a? = 0.04 ± 0.01. Experimentally, the alpha particle generated TL signal was measured with the irradiated side both facing and away from the photomultiplier in order to measure TL light self-absorption with the result µd = 1.32 ± 0.03 (1 SD), and ?a? = 0.065 ± 0.01 in reasonable agreement with theory and previous measurements of the fast neutron relative TL response. The very low sensitivity of LiF:Cu,Mg,P to high LET particles is a microdosimetric effect arising from the very rapid saturation of the TL signal at high ionisation density.
