Abstract:
In this study, long-term changes in radioactivity levels in the agricultural soil were assessed by a method in which the major processes contributing to the accumulations of radionuclides in the topsoil were taken into account. Four agricultural regions with different crops and agricultural conditions were investigated. The results indicated that long-term cultivation caused the accumulations of 226Ra and 210Po in the topsoil and the rates correlated strongly to plant types, fertilization, and irrigation features. This research is used as the pre-primary base to decide the cultivation method that is relevant to the selection of plant varieties, fertilization and irrigation methods.
