LIF-MG, CU, P TL DETECTORS WITH ADJUSTABLE ENERGY RESPONSES

When used for tissue-equivalent monitoring, in accordance with ICRU Reports 39 (1985) and 43 (1988), the thermoluminescence material LiF:Mg, Cu, P shows an 'under-response' to low-energy photons. This paper explores a new way to increase its low-energy response effectively, and to make it adjustable to some extent, by adding elements with high Z(eff). At the same time its excellent TL performance is maintained. Different concentrations of heavy elements are needed to satisfy the requirements for the ICRU quantities H(p)(10) and H*(10).
