UPTAKE OF STRONTIUM, CESIUM AND SOME OTHER FISSION PRODUCTS BY PLANTS AND THEIR ACCUMULATION IN CROP YIELD
The results of investigations conducted by the authors on the uptake of strontium-90, cesium-137, cesium-144, zirconium-95, ruthenium-106, and some other fission products by various agricultural plants summarized. Data on the distribution of the elements in plants and their accumulation in different parts of the crop plants as a function of biological characteristics of the plant environmental conditions are given. Possible agrochemical and agrotechnical aspects of the problem of controlling processes responsible for the amount of fission products accumulated and the ratio between strontium and calcium, and cesium and potassium in crop plants are considered. The results of the investigations show that the accumulation of railioactive fission products during the vegetative period increases with the growth of the above-ground mass of the plant. Reproductive organs of plant accumulate radioisotopes of strontium and cesium in greater amount them other fission products. Data are tabulated. (C.H.)
