摘要：

Powders of the 30Y(2)O(3)center dot 30P(2)O(5)center dot 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-gamma = 0.22 +/- 14% Gy accompanied gamma absorbed dose. The absorbed dose of d + D neutrons was D-n = 1.43 8% Gy with D-gamma = 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/TL gamma)/(D-n/D-gamma)](d+Be) = 0.04 +/- 60% and [(TLn/TL gamma)/(D-n/D-gamma)](d+D) = 0.11 +/- 43%.
