Abstract
Powders of the 30Y2O3·30P2O5·40SiO2 vitroceramic were irradiated with broad spectrum d+Be (Eneutron = 0-14.5 MeV) and quasi-monoenergetic d+D neutrons (Eneutron = 12.4 ± 0.22 MeV). The absorbed dose of d+Be neutrons was Dn = 2.52 ± 8% Gy with Dγ = 0.22 ± 14% Gy accompanied gamma absorbed dose. The absorbed dose of d+D neutrons was Dn = 1.43 ± 8% Gy with Dγ = 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 [(TLn/TLγ)/(Dn/Dγ)]d+Be = 0.04 ± 60% and [(TLn/TLγ)/(Dn/Dγ)]d+D = 0.11 ± 43%.Entities:
