摘要
为更加高效、精准地测量氡钍子体浓度,探讨了一种测定氡钍子体测量中滤膜自吸收系数的新方法。该方法在不更换滤膜的基础上引入了活度累积函数,计算得出了连续测量过程中的测量次数与滤膜自吸收系数的关系,以及滤膜的自吸收系数与使用次数的关系。
For more efficient and accurate measurement of radon and thorium plasma concentration,this paper discusses a measurement in the determination of un- equilibrium radon and thorium membrane from a new method for absorption coefficient. On the basis of this method without replacing filter membrane activity accumulation function is introduced. By calculated and designed experiment,the membrane filter is used in a number of measurements in the process of continuous measurements,the relationship between membrane absorption coefficient and the number in the continuous measurements and the relationship between the absorption coefficient and the number of membrane usage are obtained.
