【摘要】：為測(cè)量拉薩地區(qū)飲用水源總α放射性,并評(píng)定測(cè)量結(jié)果不確定度,依據(jù)行業(yè)標(biāo)準(zhǔn),測(cè)量該地區(qū)飲用水源總α放射性,并根據(jù)計(jì)算公式和不確定度分析實(shí)驗(yàn)評(píng)定不確定度主要來(lái)源及其大小。測(cè)量結(jié)果表明:該地區(qū)飲用水源總α放射性均較低(≤0.05 Bq·L~(-1))。測(cè)量不確定度分別為:樣品源測(cè)量不確定度為19.31%;儀器效率刻度不確定度為2.28%;源的制備不確定度為1.89%;水樣殘?jiān)淮_定度為0.26%;水樣體積不確定度為0.05%。
[Abstract]:In order to measure the total 偽 -radioactivity of drinking water source in Lhasa area and assess the uncertainty of the measurement result, the total 偽 -radioactivity of drinking water source in Lhasa area was measured according to the industry standard. According to the calculation formula and uncertainty analysis, the main sources and magnitude of uncertainty are evaluated. The results show that the total 偽 -radioactivity of drinking water in this area is lower (鈮，
