Abstract
It is difficult to detect low intensity γ radiation by using traditional γ radiation detection technique in a close distance n, γ commix pulse radiation field with very high intensity neutron radiation. PbWO4 and CeF3 which are newly developed inorganic scintillator in our country have been studied. Photoelectricity detector systemes which have high γ sensitivity and relative insensitive to neutron and fast time response were assembled by using CeF3 and photomultiplier tube. The ratio of signaltonoise for γ ray detection can be up to more than 10 times in close distance n, γ commix pulse radiation field by using this detector system.
