研究了一种能获取总测量周期内任意时段任意能区α能谱数据的α能谱数据重建测量方法,应用该方法解决了空气中~(222)Rn和~(220)Rn子体水平优化测量中时间段重叠的问题,并在ORTEC八通道α谱仪上实现了空气中~(222)Rn和~(220)Rn子体水平自动、快速及可靠的测量.

A method for superposing spectroscopy was developed and it can inquire simultaneously any energy span α spectroscopy of radon progeny and thoron progeny for any period. When measurement period was overlapped in an optimized α spectrum method for measuring radon progeny concentration and thoron progeny concentration in air the spectrum superposition method resolves this problem. So it can measure quickly and reliably radon progeny concentration and thoron progeny co...
