| 中文摘要 |
| 报道了本实验室1991-1994年间参加WHO-IRC和IAEA-AQCS组织的环境样品放射性测量国际比对工作。用2台HPGeγ谱仪,相对方法和效率曲线方法测量了土壤样品、沉积物样品和水介质样品；用自吸收校正方法测量了生物样品。对WHO-IRCNo.57Vi300号样品,在28个报出数据的实验室中,本实验室测量值与推荐值的平均相对偏差最小,为3.04%. |
| 英文摘要 |
| This paper reports the WHO-IRC and IAEA-AQCS international intercomparison that author's laboratory had participated during 1991-1994.The samples were measured with 2 HPGe γ spectrometers.The soil,sediment and water samples were measured by relative method and efficiency curve method.The biological samples were measured by self-absorption correction method.The relative deviation of measured value from recommended value were analyzed for WHO-IRC No.57 Vi300 sample.It has been given that the average deviation of the results is minimum,i.e.3.04%. |
