Abstract:In this study, tritium water was administered into simulated Chinese cabbage( Brassica chinensis )\|soil system in mode of simulated irrigation and rainfall to study its migration and distribution in each component of the system. The objective of this study are: (1) to evaluate accumulation and distribution of tritium water in Chinese cabbage when treated with different method; (2) to clarify distribution of tritium water in soil profile.\;Four concrete pools with dimensions of 1m×1m×0\^3m were constructe...
