Line 423:
With [[Environmental radioactivity#Soil|radiocaesium binding less with humic acid, peaty soils]] than the known binding "fixation" that occurs on [[kaolinite]] rich clay soils, many marshy areas of Ukraine had the highest soil to dairy-milk transfer coefficients, of soil activity in ~ 200 kBq/m<sup>2</sup> to dairy milk activity in Bq/L, that had ever been reported, with the transfer, from initial land activity into milk activity, ranging from 0.3<sup>−2</sup> to 20<sup>−2</sup> times that which was on the soil, a variance depending on the natural acidity-conditioning of the pasture.<ref name="nih.gov"/>
In 1987, Soviet medical teams conducted some 16,000 [[Whole-body counting|whole-body count]] examinations on inhabitants in otherwise comparatively lightly contaminated regions with good prospects for recovery. This was to determine the effect of banning local food and using only food imports on the internal body burden of radionuclides in inhabitants. Concurrent agricultural [[countermeasure]]s were used when cultivation did occur, to further reduce the soil to human transfer as much as possible. The expected highest body activity was in the first few years, where the unabated ingestion of local food, primarily milk consumption, resulted in the transfer of activity from soil to body; after the dissolution of the USSR, the now-reduced scale initiative to monitor the human body activity in these regions of Ukraine, recorded a small and gradual half-decadal-long rise, in internal [[committed dose]], before returning to the previous trend of observing ever lower body counts each year.{{cn}}
This momentary rise is hypothesized to be due to the cessation of the Soviet food imports together with many villagers returning to older dairy food cultivation practices and large increases in wild berry and mushroom foraging, the latter of which have similar peaty soil to fruiting body, radiocaesium transfer coefficients.<ref name="nih.gov"/>
