摘　　要：本文叙述环境样品γ能谱测量中质量控制的几个问题，主要介绍谱仪刻度中的质量控制和环境样品测量中的质量控制问题。谱仪刻度中的质量控制，包括参考源和参考样品的选择、参考样品的制备、参考源和参考样品的检验以及刻度系统的建立等。环境样品测量中的质量控制，包括本底测量、样品制备和样品测量等。最后，还概述了谱仪常见故障的判断和排除。The paper describes some aspects of quality control in γ energy spectrum mea-surements of environrnental samples with stresses on quality control in calibration of spec-trometry and measurements of envirommental samples.The quality control in calibration ofspectrometry includes selection of reference sources and samples,preparation of referencesamples,check of reference sources and samples,and establishment of calibration system. The quality control in measurements of environmental samples includes background measure-ments,preparation and measurements of samples.Finally,techniques on diaglosing and elimi-nating the routine breakdowns of spectrometer are outlined.
