N. Green et al., DISTRIBUTION OF RADIONUCLIDES IN POTATO-TUBERS - IMPLICATIONS FOR DOSE ASSESSMENTS, Journal of radioanalytical and nuclear chemistry, 226(1-2), 1997, pp. 75-78
A study of the distribution of Cs-137, Sr-90, Pu and Am in potato tube
rs has been carried out. Cesium-137 was essentially uniformly distribu
ted throughout the tuber, whereas up to about 50% of the Sr-90 activit
y was found in the peel. Results for actinides indicated that most of
the activity would be found in the peel and of this more than half wou
ld be located in the thin outermost skin. When account is taken of the
form in which potatoes are consumed in the UK, the values of soil-pla
nt transfer factors currently assumed in the NRPB model FARMLAND are r
easonable for general assessment purposes.
