摘要/Abstract

摘要： 为了解决¹⁸F活度测量的问题,本研究根据衰变规律,结合γ能谱多时段检测,提出了用γ能谱测量¹⁸F活度的方法(衰减法)。验算得到该方法的相对不确定为3.1%,初步认为该方法正确可行,能够解决γ能谱测量¹⁸F的技术难点。

Abstract: In order to solve the measurement difficulty of ¹⁸F activity, a new method (attenuation method) for measuring ¹⁸F activity with energy spectrum is put forward based on the decay law and binding energy spectrum multi-time span detection. Based on empirical calculations, the relative uncertainty of attenuation method is 3.1%. It is preliminarily believed that this method is correct and feasible, and can solve the technical difficulties in energy spectrum measurement of ¹⁸F.

Key words: positron decay, γ spectrum, activity measurement, ¹⁸F
