The measurement of isomeric yields ratios of photofission fragments was done, created in (g,f)- and (g,nf)- reactions. Average angular momentums of heavy and light fission fragmentations of 235U and 239Pu nuclei have been defined, which were irradiated of bremmsstrahlung photons with end-point energy near 9.6 and 9.8 MeV, properly. The effects of shells, odd and even-even effects have been observed in fissioned nuclei. Researches of Chernobyl radionuclides vertical migration were carried out inside the 5-км area of ChNPP in "Red forest" and "Lake Glubokoe" territories. Presence of 60Co, 90Sr, 134,137Cs, 154,155Eu, 241Am and 238-240Pu isotopes was determined to the 30 cm depth. Similarity of isotopes behavior was shown in moistened automorphed soils. Periods of semiclearing of upper 5-cm soil layer was obtained for the researched soils. The periods of semiclearing of upper 5 cm soil layer from transuraniums (241Am and 238-240Pu isotopes) are similar to the periods of semiclearing from 137Cs, 90Sr and are equal to 30 years.
