The influence of liming of soils of honey fields with high pH on the intensity of the transition of cesium-137 and strontium-90 to protein production of beekeeping, in particular, flower pollen and pergo, was studied. This protein product contains about 250 substances and mineral elements: proteins and non-protein nitrogenous compounds – 20-25 %, sugars (sucrose, glucose, fructose, etc.) – 13-35 %, starch – 1-25 %, fiber – 3 -20 %, polovin – 6-20 %, crude fat – 2-14 %, ash – 1-6 %, water – 20-30 %. Pollen contains arytenoids, flavonoids, anthocyanins, higher alcohols, growth and other substances. In ashes of pollen, a lot of mineral elements, % of total ash: potassium 20-45, magnesium – 1-12, calcium – 1-15, silicon – 2-10, phosphorus – 1-20, iron – 0,1, sulfur – 1, manganese – 1.4. Other elements that affect the vital activity of the organism are also revealed. Beetroot obnizhya is used in the food industry, has antimicrobial effect, stimulates the immune system of the body, is used in cardiovascular diseases of the stomach and kidneys. The high efficiency of use of bee antlers in the treatment of diseases of the nervous system, lungs, liver, kidneys, glands of the internal secretion, vascular diseases of the brain, gastrointestinal tract, rheumatoid arthritis is established. Bee ankles increase appetite and overall body condition. Due to the high content of biologically active substances, it is widely used to increase the immunity of the body during the period of illness and surgical operations. Anesthetics also affect the process of hematopoietic, and increases hemoglobin and red blood cells. Agricultural honey plants are a powerful source of nectar and pollen, which are raw materials for the production of bee products. The main representatives are winter and spring rape, sunflower, buckwheat, turbot. Winter rice was grown in areas with soil pH of 4.7 with specific activity of cesium-137 – 31.0 and strontium-90 – 2.7 Bq / kg. Liming of soil under winter rape was carried out at the rate of 9 t / ha of brushwood along the surface of the soil with subsequent flooding. Limestone acidic soils with a pH of 4.7 reduced the acidity of the aqueous medium to 6.8. Reducing the acidity of the soil from pH 4.7 to 6.8 contributed to a decrease in the specific activity of cesium-137 in beer overgrowth by 40.0 %, in a perace – by 42.9 %, and by strontium-90, respectively, by 43.3 % and 42, 89 %. Specific activity of cesium-137 and strontium-90 in protein beekeepers did not exceed DR-2006. The coefficient of accumulation of cesium-137 and strontium-90 in beer overwork, produced from winter wheat rape, decreased by 31.8 % and 35.7 %, respectively – by 29.6 % and 31.6 % respectively. The greatest radiological efficacy was achieved with respect to cesium-137 in beer overwork, its accumulation decreased by 66.7 %, strontium-90 – in a proxy by 3.4 times.

Comparing the intensity of the accumulation of radionuclides in protein production of beekeeping for liming soil with a pH of 4.7, it is necessary to note the higher efficiency of reduction of strontium-90 compared to cesium-137. This tendency is observed due to an increase in calcium soils, the presence of which depends on the intensity of the assimilation of plants by strontium-90. Thus, the intensity of the reduction of strontium-90 in the bee-wormhole was 2.5 times lower; the recipe was 14.4 times compared to the cesium-137 for liming the soils. Bee families who harvested pollen from winter rape, which was grown on soils without liming, produced a smaller amount of protein products. Families that harvested pollen from winter rape for liming soil produced more bee-wormwood by 18.2 % and perg, by 6.0 %, compared with a soil pH of 6.8. Along with this, it was found that the specific activity of cesium-137 and strontium-90 in the perogus was higher in 2.8 and 7.0 times compared to bee-wormholes, respectively.

Key words: bee apple, perg, soil, radionuclides, honey fields, cesium-137, strontium-90.
