2 Method for Estimation of Radio-Ecological Pollution of the Environment The method is in the sphere of environment monitoring and applied for study of radionuclide content in tree growth rings and for timing maximum inflow of radionuclides into the environment. The technology makes possible to carry out a retrospective estimation of the radiation territory pollution with fissionable radionuclides (U235, Pu, Am, Np etc) under nuclear fall-out: nuclear weapons test in atmosphere; underground nuclear explosions; radioactive waste disposals; nuclear-fuel cycle enterprises location (AEP). Application of the nuclear-physical method ensuring fixation of fission fragments of U235, Pu, Am, Np under thermal neutrons impact within the reaction (n, f) fission radiography, makes possible to date these elements in any natural objects, including tree growth rings with a high susceptibility level of (10 9 %) and reliability. Number of fission fragment treks indicates a level of the components accumulation in the environment and time of their inflow. Since the tree growth rings have a close lock-on, their study makes possible to carry out a retrospective analysis of radioactive element fall-out and estimation of their accumulation level. The technology use requires special equipment: thermal neutrons supply (research nuclear reactor or special neutron supplies). This technology does not have any analogues in Russia and abroad. Development Stage The technology is ready for implementation and is already implemented in Russia. Legal Protection Patent RU
