摘　　要：本文介绍了兰州大学现代物理系的ZF-150型中子发生器大厅内X-γ照射量率和γ能谱测量的结果。用 FJ-377型热释光剂量仪测量了中子发生器运行过程中 X、γ射线照射量率分布;用 FJ-311G γ微伦仪和 NaI(Tl)γ能谱仪测量了中子发生器在产额为3×10~9n/s条件下,运行1小时后,靶头附近的照射量率及γ谱。This paper gives the results of X,γ exposure rate and γ spectra measured in the hall of neutron generator of Model ZF-150 at Lanzhou University.The distribution of X,γ dose rate was mea-sured with TLD dosimeter during the operation of neutron generator,the exposure rate and γ spectrawere measured nearby target holder with FJ-311G dose meter and a 3″×3″Nal(Tl)detector respec-tively after the generator having been operated for one hour and under the condition of neutron yeild of3×10~9 s^(-1).
