Concentration and characterization of plutonium in soils of Hubei in central China
To study the Pu concentration and isotope ratio distributions present in China, the239+240Pu total activities and240Pu/239Pu atom ratios in core soil samples from Hubei Province in central China were investigated using Accelerator Mass Spectrometry (AMS). The activities ranged from 0.019 to 0.502 mBq g-1 and the239+240Pu inventories of 45 and ∼55 Bq m-2 agree well with that expected from global fallout. The240Pu/239Pu atom ratios in the soil ranged from 0.172 to 0.220. The ratios are similar to...[Show more]
