Abstract. The study results of dosimeters based on doped lithium fluoride and carbon C-based leucosapphire are presented for use in mixed γ-n fields. The radiation conditions were created using the radioisotope stands based on certified 60Co and Pu–α-Be sources. It is shown that the studied dosimeters are promising for recording the absorbed dose starting from 1 mGy for γ- and mixed γ-n radiation factors. The sensitivity of TLD-100H (LiF:Mg,Cu,P) dosimeters was determined to be several times higher than that of TLD-100 (LiF:Mg,Ti) and Al2O3:C. A sensitivity parameter was introduced to quantify the efficiency of dosimetric materials for fixed irradiation conditions. The dependence of luminous intensity on the dose or irradiation time for γ- and mixed γ-n irradiation is shown.
Keywords: radiation stands, ?-n radiation, dosimeters, lithium fluoride, leucosapphire.
