Effect of Local Conditions on Coefficient of Radionuclide Transfer Through Food Chains
This Chapter presents the results of studies carried out for years in some regions of the Soviet Union that have a relatively high migration of global 137Cs to vegetation. This is especially characteristic of wooded lowlands where soils are, for the most part, made of peat bog and grassy-podzol sand varieties. An increased 137Cs migration to vegetation is found to result primarily from lack (or low content) of clay minerals, for example, hydromica, in these soils. Further contribution is made by a limited content of mobile K and a high water content. For these soils, the 137Cs transfer coefficient is ten times higher than the average for the country. As a result, the 137Cs content of local foods, particularly of milk, is 10 to 100-fold higher.
