[Food fibers--blockers and decontaminants of the radionuclides cesium and strontium].

The Chernobyl accident and its resultant radioactive pollution of enormous areas led to long-term entrance of radionuclides into the human habitat. Among more than 200 radionuclides, the products of uranium fission in the reactor of the atomic power station, the isotopes of iodine, cesium, and strontium present the highest hazard. If iodine-131 virtually decayed by August, 1986, the long-lived isotopes of cesium and strontium will still stir the world public and scientists for many years. The authors' result show that new types of dietary cellulose and composite food additives based on alfalfa polymers have rather pronounced antiradioactive properties against Cs-137 and Sr-85. This makes it necessary to organize the manufacture of these food additives whose daily dose of 12-20 should be supplemented into human diet every day.
