Free-radical reactions in Daphnia after low doses of γ-irradiation in vivo

A violation of free-radical reactions has been found by the method of free-radical copolymerization in the two groups of Daphnia magna exposed to 100 and 1000 mGy of gamma-rays and their non-exposed first generation progeny. The method is based on a quantitative radiometric registration of the polym...

Summary:A violation of free-radical reactions has been found by the method of free-radical copolymerization in the two groups of Daphnia magna exposed to 100 and 1000 mGy of gamma-rays and their non-exposed first generation progeny. The method is based on a quantitative radiometric registration of the polymerization process that develops in the cells of a multicellular organism in tissue in proportion to the existing number of free radicals. The fact of the increased level of free radicals may be indicative of the hereditary transgenerational effect and the cause of lower survival of Daphnia in both generations. However, the effect of a reduced survival rate does not persist in the second generation, which can be explained by the effect of radiation on the embryos of the first generation after acute irradiation of parents.
