Karazin popup.description2 Changes to take place in biological objects under SHF, laser and x-ray irradiation were investigated on the organism, cellular and subcellular levels. It was found, that SHF field increase chromatin condensation and nuclei electronegativity degree. There was displayed influence of laser irradiation on transvection effect. Effects of genetic stress caused by izogenization of chromosomes on drosophila's genome and as a result on increasing of of not equal crossingover and DLM frequency were found. It was shown that izogenization of chromosomes can be the factor of some loci genetic instability, that is possible to be the resistance against gomozigotization of genome. The influence of laser irradiation on reproductive ability of drosophila males was found. There was investigated display of stimulation effect of adaptive doses of x-ray radiation on cellular and organism level in early plant ontogenesis.
