属于铀系的放射性核素对（214）Bi和（214）Po干扰核设施辐射管理所需的气载放射性核素测量。由于（214）Po的半衰期短（164 μ s），（214）Bi（β）和（214）Po（α）之间的时间间隔比人工放射性核素短得多。本研究的目的是发展一种基于β-α符合方法的新的分析方法（时间间隔分析），用于选择性测量（214）Bi-（214）Po。所开发的方法被应用到一个实际的灰尘过滤器的测量。TIA系统是一种高效率的背景减除滤波器测量系统。
The radionuclide pair (214)Bi and (214)Po which belongs to the uranium series interferes with airborne radionuclide measurement needed for the radiation management of a nuclear facility. Time intervals between (214)Bi (β) and (214)Po (α) are much shorter than artificial radionuclides due to the short half-life of (214)Po (164 μs). The purpose of this study is to develop of a new analytical method (time interval analysis: TIA) based on the beta-alpha coincidence method for selective measurement of (214)Bi-(214)Po. The developed method was applied to an actual dust-filter measurement. The TIA system was highly effective in measuring of the filter with background subtraction.
