Neutron-gamma mixed field dosimetry using a 6LiF:Mg,Cu,P thermoluminescent dosimeter

Satisfactory discrimination between the neutron and gamma components in a mixed neutron-gamma field is one of most important objectives dosimetry. One common techniques for estimating dose fields two peak method. This method has been applied using dosimeters such as LiF:Mg,Ti, but present work, 6LiF:Mg,Cu,P dosimeter used, whose thermoluminescence sensitivity much higher than LiF:Mg,Ti dosimeter, therefore, if appropriate results are achieved, it can drastically reduce estimation threshold. Applicability thermal radiation was studied. The ratio area underneath high temperature glow to dosimetry this phosphor an Am-Be 0.127, while pure ray 137Cs 0.039. calibration curves were obtained by separately irradiating chips with known doses. Results show that be used estimate contributions doses
