Abstract

LiF based thermoluminescent materials are the most used passive detectors in the field of radiation protection. For personal and area dosimetry in mixed neutron and photon fields, 6LiF and 7LiF TLD pairs are employed for the simultaneous determination of neutron and photon doses. Therefore, an accurate knowledge of their sensitivity to photons and thermal neutrons is essential. Aimed at providing reliable sensitivity data for new LiF based TL materials, an experimental study was carried out in the framework of a collaboration between INFN Frascati National Laboratories and ENEA, Italy. The 6LiF(Mg,Cu,P) material from TLD Poland, was specially manufactured in six versions with different sensitive thickness (t = 40, 60, 80, 100, 150 and 230 mg.cm-2), which implies different neutron and photon sensitivity. Together with the 7LiF(Mg,Cu,P) material, namely MCP-7, all seven types of TLDs were irradiated in reference beams of photons and thermal neutrons, at the calibration facilities of INFN and ENEA. The study provides a set of sensitivity data and discusses the performance of the investigated materials for the dosimetry of mixed neutron and photon fields. © 2005 IEEE.
