Here we have collected data on the distribution of gross-α and gross-β activities in groundwater in several provinces including the Haihe River Plain, Liaoning, Chongqing City, Jiangsu, Zhejiang, Guangxi and Hainan. These radioactivity signals reflect emission from several radioactive sources and are considered the first screen of groundwater quality for radioactivity control. The source of gross-α activity in groundwater is mainly the decay of natural uranium and thorium isotopes. For gross-β activity, decay of natural potassium-40 and beta emission from uranium decay series are important sources. In general, gross-α and gross-β activities in groundwater considered here range at ND (non-detectable) to 362 mBq/L and at 14 to 779 mBq/L, respectively. These values are lower than the permissible limits of the WHO (500 mBq/L for gross-α and 1000 mBq/L for gross-β) for drinking water. Although the general data suggest acceptable range of radioactivity in the groundwater of the areas included here, it is important to mention that possible additional radioactivity dose may emanate from rapidly decaying gaseous phases such as radon.
