LiF(Mg,Ti)-M thermoluminescence dosimestries(TLDs)are studied and their uniformity,repeatability and linearity of the response toγrays are compared.The mean and standard deviation of their readout values are measured.The variable coefficients of their sensitivities under different absorbed doses are analyzed and the influence of the irradiation of high dose beyond linearity upper limit on linearity is obtained.The results indicate that the LiF(Mg,Ti)-M TLD produced by Beijing Research Institute of Chemical ...
