INTENSITY OF CESIUM-137 ACCUMULATION IN FLOWER POLLEN OF CORN AT DIFFERENT pH OF SOIL ENVIRONMENT

137Сs is concentrated in soils and a continuous cycle, the intensity of movement which depends on number factors, particular type soil, its composition properties, botanical origin plants others. . It was found that under same ecological conditions accumulation coefficient 137Cs distribution honey can differ up to 3 times. The migration radionuclides into vegetation lower with high levels nutrients, compared low-nutrient soils. This feature inherent both agricultural forest High migr ation observed sod-podzolic sandy soils, while chernozems it relatively lower. Soils lands studied areas are mainly sod-podzolic. They characterized by low content humus trace elements, sometimes acidity, increase translocation their products, pollen. After half-life 137Cs, released environment after Chernobyl accident, there certain pattern contamination protein products beekeeping depending type, harvesting period lands. Along this, should be noted exceedance permissible only for cesium-137 territory soil this element exceeded 4 Ki / km2. On basis fact pollen main raw material production beekeeping, further research aimed at studying measures improve quality order reduce bee persimmon. corn studied. lowering pH from 4.6 7.7 contributes decrease maize activity 9.7 Bq kg 5.8 kg, hazard factor 0.049 0.029 0 , 28 0.14.
