Abstract

The tritium deposited in the soil formed the non-exchangeable organically bound tritium (NE-OBT). Most of the NE-OBT locates at the surface. In this study, higher NE-OBT activity appeared at the sampling sites in the prevailing wind direction. The distribution of NE-OBT activity in soil particle with different particle size implied that the NE-OBT might originate from soil organic matter. According to the correlation analyses, in the soil with particle size less than 53 μm, the NE-OBT might originate from soil organic matter, and in the soil with particle size between 250 and 2000 μm, it originated from HTO.
