摘要
In the field conditions, the long-term (2013-2015) small-plots experiment was carried out for evaluation of radiological efficiency of application of ameliorants as the countermeasures for reduction of the Cs-137 uptake to herbage at the Peat-boggy (Histosols) soils of Ukrainian Polissya. At the late stage after the Chernobyl accident, the average radiological efficiencies of application of sand (175-200 ton ha(-1)) and ferrocyn (0.2 ton ha(-1)) as the ameliorants were rather low ranging from 0.8 to 1.6. Application of 4 ton ha(-1) of chalk and 5 ton ha(-1) of peat ash decreased 1.7-1.9 times the 137Cs activity concentrations in plans. The highest radiological efficiencies, 4.4 +/- 2.0 and 7 +/- 2, were reached at applications of chalk-ferrocyn ameliorant (4 + 0.2 ton ha(-1)) and ferrocyn-bentonite absorbent HZH-90 (30 ton ha(-1)), respectively.
