摘要
掺铈氯化镧晶体(Lacl3:Ce)是国际上最新研制的无机闪烁快响应晶体,其具有对γ探测能力强,时间响应快,中子、γ分辨能力高等特点。在放射性标准源场中对首批国产掺铈氯化镧晶体配光电倍增管的γ灵敏度进行了测量,测量结果表明国产新型Lacl3:Ce无机晶体对1.25 MeV和0.66 MeVγ射线的探测能力约为NaI晶体的80%左右。此类晶体可作为低强度快脉冲γ辐射测量的候选晶体。
Lacl3 ：Ce scintillator was the inorganic fast-response crystal which have been developed newly. It has some strong＇points, for example, high γsensitivity, fast time-respond and high neutron/γ differen- tiate etc. Two kinds of energy γsensitivity in the standard radiation field was measured. The result show： the detecting capability of the homemade Lacl3 ：Ce scintilltor is the 80% of NaI when the volume is same. It may be used in low intensity γ pulse radiation field.
