Abstract
PREDICTIONS of the potential hazards from fall-out radioisotopes in man's food chain have often been based on ion-pair relationships1,2. For example, because of close chemical similarities between strontium and calcium, the transfer of strontium-90 through biological materials has been correlated with calcium. The ratio of strontium-90/calcium of the tissue to the same ratio in the substrate, that is, strontium-90/calcium(tissue)/strontium-90/calcium(substrate), has been termed by Comar the observed ratio3. More recently caesium-137 hazards have been considered in terms of caesium-137/potassium ratios. Certain applications of these ratios have been criticized by Kornberg4, and the conditions necessary for their valid application in hazard assessment discussed. This report presents results which demonstrate the absence of any consistent relationship between the accumulation of caesium and potassium in bean plants, and further demonstrates the limited applicability of caesium-137/potassium ratios in hazard predictions.
