Abstract: ► In 1986 the Chernobyl accident contaminated soils across Europe with ¹³⁷Cs. ► In 2008/2010 we measured ¹³⁷Cs in 8 peaty soils from a transect across Scotland. ► The ¹³⁷Cs activities were between 2.8 and 14.4 kBq m⁻², decay corrected to 1986. ► The mean migration depths of ¹³⁷Cs were between 8.2 and 17.4 cm. ► Clay minerals alone in the soils did not control the downward migration of ¹³⁷Cs.
