Grain size dependence of lyoluminescence sensitivity in mannose

Abstract

In mannose, grain-size and grain-size band width have been shown to have considerable effect on lyoluminescence (LL) yield and fading characteristics. The effects of these on sensitivity and reproducibility of dose interpretation are reported in this work. Dose reproducibility of better than 0.3% is recorded among narrow grain-size band samples while dose coefficient of 5.31 change in LL yield per Gy is obtained for the more uniform grain-sized samples.
