【摘要】 本文以一个实际环境样品测量为例,逐项评估了环境热释光剂量测量中各主要不确定度分量,获得了测量结果的合成扩展不确定度。评估结果表明:环境热释光剂量测量不确定度评定中,主要应考虑的不确定度分量为测量重复性引入的A类不确定度以及刻度因子引入的B类不确定度。更多还原

【Abstract】 Taking an ordinary sample as an example,the main components of uncertainty of thermoluminescence dosimetry(TLD) in environmental monitoring were evaluated,and the expanded combined uncertainty of the measurement result was calculated in this paper.The results showed that the main components of uncertainty in environmental accumulative TLD measurement were the type A uncertainty from repeatability and type B uncertainty from calibration factor.更多还原
