Thermoluminescence properties of 30Y2O3·30P2O5·40SiO2 vitroceramics in mixed neutron-gamma fields

Abstract Powders of the 30Y 2 O 3 ·30P 2 O 5 ·40SiO 2 vitroceramic were irradiated with broad spectrum d+Be (E neutron = 0–14.5 MeV) and quasi-monoenergetic d+D neutrons (E neutron = 12.4 ± 0.22 MeV). The absorbed dose of d+Be neutrons was D n = 2.52 ± 8% Gy with D γ = 0.22 ± 14% Gy accompanied gamma absorbed dose. The absorbed dose of d+D neutrons was D n = 1.43 ± 8% Gy with D γ = 0.21 ± 14% Gy gamma absorbed dose. The thermoluminescence (TL) induced in the vitroceramics was studied. Both the gamma and neutron component contributed to the TL signals. The relative neutron sensitivities were [(TL n /TL γ )/(D n /D γ )] d+Be = 0.04 ± 60% and [(TL n /TL γ )/(D n /D γ )] d+D = 0.11 ± 43%.
