Effects of X, β and VUV irradiations on LiF:Eu3+ were studied and compared to those induced in nominally pure LiF. In the pure crystals thermoluminescence (TL) could be excited by X- or β-rays: in LiF:Eu+ the TL could also be excited by VUV radiation with excitation maxima at 190 nm and near 125 nm. The 190 nm maximum coincided with a weak absorption band, recorded in the irradiated crystals. A strong optically stimulated thermoluminescence (OSTL) also appeared in pure crystals, which had previously been X- or β-irradiated at RT and then illuminated at LNT with 190 nm. The fact that the OSTL and the TL showed the same excitation maxima in both crystals, indicates that they are due to the same trapping states. Different emission bands were, however, recorded by the same excitation in LiF:Eu3+ and pure LiF samples. Results have shown that the radiation sensitivity of the Eu3+ doped samples is by an order of magnitude higher than that of pure LiF crystals but by about an order of magnitude lower than that of LiF:Mg,Ti (TLD100).
