Abstract: The effect of acid irrigation with and without liming on the vertical transport of Chernobyl-derived ¹³⁴Cs in the soil was investigated in a Norway spruce stand by field experiments. For this purpose seven plots with different treatments were established. After 5 years of observation to detect differences in the residence half-time’s of ¹³⁴Cs in the various soil horizons with respect to the control sites, the plots were sampled at 18 individual pits. No effect on the residence half-time of ¹³⁴Cs was observed for ‘normal’ irrigation (pH 5.3) as compared to the control in all organic horizons.
