Investigations have continued on the extent to which Sr/sup 89/ and Cs/ sup 137/ are transferred to the edible parts of cabbage and potato after aerial contamination at various times in the growing season. Significant trends in the concentration of Sr/sup 89/ and Cs/sup 137/ in the hearts of cabbages and Cs/sup 137/ in potato tubers were observed with maximum values after contamination in the middle of the season. A similar trend in the concentrations of Sr/sup 89/ in potato tubers was suggested, but no significant differences could be established. The range of concentrations was of the same order as those found in previous years. The present and earlier results have been used to assess the relationships in the field between the deposition of Sr/sup 90/ and Cs/sup 137/ and their concentration in crops. These relationships show, at least for wheat and potatoes, reasonable agreement with those deduced from surveys of Sr/sup 90/ and Cs/sup 137/ in foodstuffs resulting from the worldwide dissemination of fall- out from nuclear weapons.
