Abstract

Thermoluminescent (TL) properties of two concentration series lithium potassium yttrium fluoride doped with praseodymium (LiKYF₅:Pr³⁺) and potassium yttrium fluoride doped with thulium (KYF₄:Tm³⁺:) have been investigated after gamma and neutron irradiation. The main purpose of this research is to see whether these materials are suitable for gamma and/or neutron dosimetry purposes. It has been found that the compounds of both series are sensitive to ⁶⁰Co gamma radiation. A maximal TL sensitivity is found for LiKY_0.99Pr_0.01F₅ and KY_0.99Tm_0.01F₄. However, for this doping level the intensity of the TL glow peak is about 7 times less than that for LiF:Mg,Ti (TLD-700). The TL sensitivity to thermal neutrons is relatively higher than that to ⁶⁰Co photons. No TL sensitivity to fast neutrons was observed.
