摘要：

Radiation measurements are critical in radiation physics, and it is vital to recognize the potential adverse effects on human health. Ra-226 constitutes the primary naturally occurring radioactive element in soil, holding substantial effect on both human health and the environment. Traditional method for determining Ra-226 activity through gamma spectrometry necessitates an extended sample holding time to allow for the ingrowth of radon (approximately seven Rn-222 half-lives, equivalent to 27 days). It is essential to develop a novel method for rapidly and accurately determining the activity o...
