AbstractUse of fallout Cs-137 for measuring soil erosion rates requires an accurate estimate of the mean areal activity of Cs-137 of an uneroded reference site. To study the short-range variability of Cs-137 in a forest soil, 16 profiles were sampled in a small area (8 x 8 m). Variability was relatively low (CV = 16%), so that the mean areal activity (3163 Bq m-2) at this reference site was estimated with a relatively low allowable error (< 10%) at relatiVely high confidence level (95 %). To obtain a satisfactory estimate of the mean areal activity of Cs-137 of reference sites, particularly those located in forest areas, it is suggested to collect at least five subsamples, 1-10 m apart and composite them into a single sample for analysis.
