AB  - In this study, tritiated water (HTO) and organically bound tritium (OBT) activity 
      concentration at different depth soil layers (0-5 cm, 5-10 cm, 10-15 cm, 
      15-20 cm, and 20-25 cm) were measured in uncultivated and cultivated soil samples 
      collected in the vicinity of the Qinshan nuclear power plant (QNPP) in July, 
      September, and December 2018. The concentration difference, the spatial and 
      temporal distribution, the seasonal variation, and the OBT/HTO ratios were 
      investigated. The average ratios of HTO concentration between uncultivated and 
      cultivated soil moisture were 1.20 +/- 0.24, 1.39 +/- 0.46 and 0.95 +/- 0.14 in July, 
      September and December, respectively, the corresponding values for OBT were 
      1.17 +/- 0.31, 1.22 +/- 0.49 and 1.08 +/- 0.28. In generally, the highest HTO 
      concentration in uncultivated soil was found for the topsoil (0-5 cm) in July and 
      September and for the deeper soil layer (20-25 cm) in December, while for 
      cultivated soil, the highest levels were found for the middle layer soil in July, 
      for the topsoil (0-5 cm) in September, and for the deeper layer soil (20-25 cm) 
      in December. Both soils, the vertical profile distribution of OBT concentration 
      showed no consistent tendency, and there were no significant differences in the 
      HTO and OBT concentrations between different soil layers, except for the highest 
      concentration. Whether uncultivated soil or cultivated soil, HTO activity 
      concentrations showed an apparent spatial distribution and seasonal variability, 
      decreasing with the distance to the release sources and with sampling time, while 
      OBT concentrations showed lower spatial and seasonal variability than HTO. In 
      most cases, the OBT/HTO ratios were less than 1, with average values of 
      1.01 +/- 0.48 and 1.06 +/- 0.86 for cultivated soil and cultivated soil samples, 
      respectively. The results of this work suggest that farming may affect tritium 
      behavior in soil, while the spatial and temporal distribution of tritium is only 
      slightly impacted.
