Absorption of radioelements from the soil by various vegetables grown under normal condition of cultivation; Absorption de radioelements du sol par divers legumes cultives dans les conditions de la pratique

Abstract

Various vegetables were cultivated in 4 different types of soil, having received, or receiving periodically, strontium-90 or caesium-137 in fairly strong doses, in order to facilitate the measurement of the fraction of these radioelements taken up by the vegetables. In sandy soil, whole plants absorbed 2 to 3 per cent of Sr and 3 to 9 parts per thousand of Cs approximately; in clay soils, 1 to 6 parts per thousand of Sr and 0,2 to 2 parts per thousand of Cs; Cs, however, migrates relatively more than Sr in fruits or storage organs. The experiments confirmed that the quotient of the ratios {sup 90}Sr/Ca in the vegetables and in the ploughed layer varies comparatively slightly; these would be a certain safety margin in assuming this ratio to be slightly above unity (to be confirmed after homogenising the ploughed layer). In view of the fact that in an arid climate it is necessary to apply several tens of litres of irrigation water (up to 50) in order to produce 1 kg of vegetables (fresh whole plants) and that furthermore, the radioelements of the residue from the crop harvest return to the soil, it can be expected that the limit of  More>>

(author) [French] Divers legumes ont ete cultives dans 4 types de sols differents, ayant recu ou recevant periodiquement du strontium-90 ou du cesium-137, a doses relativement fortes, de maniere a faciliter la mesure de la fraction de ces radioelements absorbee par les legumes. En sol sableux, les plantes entieres ont absorbe 2 a 3 pour cent de Sr et 3 a 9 pour mille de Cs environ, en sol argileux, 1 a 6 pour mille de Sr et 0,2 a 2 pour mille de Cs; mais Cs migre relativement plus que Sr dans les fruits ou les organes de reserve. Les experiences ont confirme que le quotient des rapports {sup 90}Sr/Ca dans les legumes et dans la couche labouree est relativement peu variable; on conserverait une certaine marge de securite en adoptant pour ce rapport une valeur un peu superieure a l'unite (a preciser apres homogeneisation de la couche labouree). Etant donne que sous climat aride, il faut appliquer plusieurs dizaines de litres d'eau d'irrigation (jusqu'a 50) pour produire 1 kg de legumes (plantes entieres fraiches), et qu'en outre les radioelements des residus de recolte retournent au sol, on peut prevoir qu'a la limite d'accumulation, 1 kg de certains legumes pourra contenir autant de chaque radioelement que plusieurs dizaines de litres d'eau d'irrigation.
