Abstract
A method is reported whereby aqueous solutions containing weak beta emitters are dispersed as stable emulsions in liquid scintillator counting solutions. This permits the routine counting, with about 10-percent efficiency, of large numbers of samples containing tritium. Self-absorption does not present a problem when less than 5 percent aqueous phase is present.
摘要
据报道，有一种方法可将含有弱β发射体的水溶液作为稳定乳液分散在液体闪烁计数溶液中。这使得大量含氚样品能够以约10%的效率进行常规计数。当水相含量低于5%时，自吸收问题不存在。
