Dose response of the individual peak for LiF:Mg,Ti (TLD-100) and LiF:Mg,Cu,P (GR-200A) TL materials at the photon energies of 30, 104, 1250 keV

The dose responses for LiF:Mg,Ti (TLD-100) and LiF:Mg,Cu,P (GR-200A) have been examined at the photon energies of 30, 104 and 1250 keV. A GCA program has been used for the deconvolution of the glow peaks and the behaviours of the individual peaks have been analysed. For TLD-100, an increasing supralinearity was observed for the higher temperature peaks, and the supralinearity at 30 keV was lower than that at 1250 keV. For GR-200A, peak 4 showed supralinearity around 10 Gy. A possible correlation seems to exist between the energy response and dose response. A brief discussion and explanation are provided.
