【摘要】 用鼓泡法制备出了58种浓度,湿度各不相同的氚化水蒸汽样品,用于对 FJ-357低能β测量仪,进行逐点刻度。样品的浓度范围为:10^-9—10^-6居里/升（相当0.5—1000MPC）,复盖4个量级,相对温度从15.7%到近于100%。用58个气样得到的电离室读数/样品浓度的平均值为（?）±σK=1.00±0.09更多还原

【Abstract】 Fifty eight tritiated water（HTO）vapour samples to be usedone by one for calibration of the Type FJ-357 low energy β surveying me-ter were in different relative humidity and concentration prepared by bubbli-ng.when the samples lay from 2.6x10^-9Ci/1 to 4.6×10^-6 Ci/1 in concentra-tion,covering about four orders of magnitude,from 15.7% to near 100%in relative humidity,for all the fifty eight samples the average value of theratio of the ionchamber reading to the concentration of the sample wasK±σ_k=1.00±0.09.更多还原
