Abstract
This paper compares the gamma‐radioactivity values determined in an intertidal ecosystem on the Atlantic island of Barra in the Western Isles of Scotland in 1989 and 1994. Distinct differences in the accumulation values in different trophic levels were detected on each occasion, but, in the intervening five years between surveys, there have also been marked reductions in the gamma counts in many different organisms of each trophic level. Gamma‐radioactivity has continued to move through the sandy soils of the machair coastal dunes system, and hence away from the rooting zone of the vegetation. The decreasing gamma‐radioactivities noted point to a shoreline ecosystem that is recovering from the input of Chernobyl fallout.

Abstract
An analysis of radioactivity in organisms inhabiting the intertidal region of the Island of Skye revealed accumulation of gamma radioactivity by specific organisms, such as lichens, to be markedly enhanced as compared with other autotrophs. The movement of radioactivity through trophic levels culminating in organisms such as the predator Nucella lapillus is described. A comparison with previous work indicates a marked decrease in the gamma count in these organisms due to a variety of factors as discussed. The importance of the position of the organism on the shore during the post‐Chernobyl contaminated rainfall is reiterated.

A detailed review of J. Ennew's The Western Isles Today, published by Cambridge University Press, 1980. The reviewer finds it to be a book that flounders on theoretical, methodical and empirical inadequacies.
