Abstract: During the period of 3 years (2013 - 2015) in terms of finely-making spot field experiments coefficients of accumulation of 137Cs (control 6,1 ± 0,8) after a single application of agrochemical countermeasures on peat-bog soils in Rokytne district, Rivne region, characterized by abnormally high bioavailability of cesium radioisotopes were obtained. In the late phase of the elimination of the Chernobyl accident, radiological averaged efficiency sandsing (175 - 200 t/ha), introduction of ferrocyn (0,2 t/ha) did not differ significantly from unity and amounted to 0,8 - 1,6 times. Liming (chalk 4 t/ha) and the introduction of peat ash (5 t/ha) reduced the 137Cs content in vegetation in 1,7 - 1,9 times. Highest radiological efficiency was achieved after applying mixture of chalk-ferrocin (4 + 0,2 t/ha) - 4,4 ± 2,0 times and ferrocin-bentonite sorbent (30 t/ha) - 7,0 ± 2,0 times.

Keywords: 137Cs, countermeasures, radiological effectiveness, peat-bog soils, Chernobyl accident.
