Evaluation of 137Cs ageing by dynamics of 137Cs/133Cs ratio in Andosol paddy fields with/without potassium fertilizer application

The mobility of 137Cs in soil decreases with time owing to fixation by micaceous minerals. Such ageing is a critical parameter for estimating and predicting annual change in 137Cs contamination risk of agricultural products. The decrease in the exchangeable fraction of 137Cs has traditionally been u...
