Abstract

Systematic tests were made in order to determine the neutron and gamma response characteristics of LiF:Mg,Cu,P detectors MCP-7s (TLD Niewiadomski) for use in boron neutron capture therapy (BNCT). The results of the tests showed that: (1) the shapes and glow peak structures of glow curves after mixed neutron-gamma irradiations differed considerably between test samples selected from two production batches; (2) all response characteristics repeated well among detectors of the same batch; and (3) sufficiently long pre-irradiation annealing at 260 degrees C (>3 min) regenerated the detectors to a stable ground state (original distribution of detector sensitivities among the sample) much better than annealing at 240 degrees C. It was concluded that comprehensive quality control tests must be made and that the optimum TLD process must be planned for each production batch of (LiF)-Li-7:Mg,Cu,P detectors intended for use in BNCT dosimetry.
