Mobility of radionuclides in undisturbed and cultivated soils in Ukraine, Belarus and Russia six years after the Chernobyl fallout

Plant uptake and downward migration of 85Sr and 137Cs after their deposition on to flooded rice fields: lysimeter experiments with and without the addition of KCl and lime

“…It is well known that radiostrontium moves faster down the soil profile than radiocesium (Cline and Rickard, 1972;Kliashtorin et al, 1994;Salbu et al, 1994;Askbrant et al, 1996). Many works (Livens et al, 1991;Salbu et al, 1994;Askbrant al., 1996) have been reported to show the localization of radiocesium with respect to the soil surface in the Chernobyl-affected areas even years after the accident.…”

“…Many works (Livens et al, 1991;Salbu et al, 1994;Askbrant al., 1996) have been reported to show the localization of radiocesium with respect to the soil surface in the Chernobyl-affected areas even years after the accident. The depth profiles without the addition of KCl and lime indicate that negligible amounts of both radionuclides were present beneath the top 20 cm of the soil.…”

Evaluation of the possibility to use the plant–microbe interaction to stimulate radioactive 137Cs accumulation by plants in a contaminated farm field in Fukushima, Japan

“…In a study conducted on contaminated paddy fields at Minami-Soma city in Fukushima prefecture, Endo et al (2012) found that radiocesium was uniformly redistributed in the soil of a cultivated field. The same depth distribution profile of 137 Cs and its redistribution due to agricultural practices including plowing was also reported for some Mediterranean soils (Gaspar and Navas 2013) and for undisturbed and cultivated soils affected by the Chernobyl accident, even several years after the deposition (Askbrant et al 1996).…”

The transfer of 239/240Pu to cow milk

“…In a study conducted during the summer of 1993, Beresford et al (2000a) measured the gastrointestinal absorption of 137 Cs and 90 Sr by dairy cattle fed freshly cut herbage collected 5 km from the Chernobyl NPP; transfer parameters to milk were also determined. Particulate fallout was known to comprise a significant amount of the total deposition to the site (Askbrant et al, 1996). They measured a true absorption coefficient (fraction of ingested radionuclide which is transferred across the wall of the gut; A t ) for 137 Cs of 0.2 which was considerably lower than previous estimates for radiocaesium incorporated into vegetation by root uptake (circa 0.8, Beresford et al, 2000b).…”
