本文介绍用于低水平环境γ测量的FJ-2005型环境γ测量仪。本机采用了涨落分析技术,能够区别来自核设施和天然辐射的γ贡献,并能自动打印γ照射率的平均值和标准偏差。仪器的灵敏度约为25×10~(-15)A/(μR·h~(-1))。
This article describes the FJ-2005 Environmental Gamma Meter for low-level environmental gamma measurements. The machine uses fluctuation analysis technology to distinguish γ contributions from nuclear facilities and natural radiation and to automatically print the mean and standard deviation of gamma irradiation rates. The sensitivity of the instrument is about 25 × 10 ~ (-15) A / (μR · h ~ (-1)).
