Values of ???-radioactivity were monitored in three sites on the Island of Skye (Hebrides, Scotland) approximately five years after the explosion of the reactor at chernobyl, USSR. The sites chosen were all closely associated and comprised a podsolized area together with two areas exhibiting substantial peat deposits. [SUP137]Cs concentrations in the vegetation were found to be low although enhanced accumulation, probably due to translocation from the leaves (or also some accumulation from the soil), occurred in the woody tissue and certain plant stroage organs. The importance of lichens as accumulators of pollutants is reiterated. The accumulation of radioactivity through trophic levels to herbivores was clearly defined. In both podsolized and peaty soils, radioactive products had migrated down through the soil profile and consequently away from the major rooting zones--Thus the chances of uptake and thence accumulation back into the vegetation become futher reduced; recovery is proceeding and this too will be linked to the half life of [SUP137]Cs.
