    THE THE DETERMINATION OF THERMAL NEUTRONS DOSE WITH TLD 100 - LiF,Ti,Mg

                                   Abstract:
The bitter discussion in the literature on the correlation of ionisation density
 of ionising radiation (LET) with the ratio of the high temperature peak to the
    usual dosimetry peak (HTR) will be presented, A possible answer will be
presented in the end of the lecture. It will be suggested to replace the use of
 the ratio of the heights by the ratio of the areas. Since convolution is time
 consuming and subjective it will be suggested to be replaced by the method of
     Regions of Interest(ROI). It will be shown that the ROI method is very
 beneficial in eliminating the problem of fading in routine dosimetry of either
gamma rays or neutrons. The current rejection of the use of the high temperature
 peak (HTP) will be shown to be wrong for the usual range of personal dosimetry
using the ROI method. It will be shown how the HTP can be used to determine the
                   thermal neutrons dosimetry. It will be sh
