Nuclear energy in Ukraine is provided by the operation of four operating nuclear power plants (15 reactors). For the next decades it is planned only to increase the capacity of this according to the “Energy Strategy of Ukraine until 2035” industry. Nuclear power plants are objects of increased danger. So, conditions should be provided to maintain environmental balance in Ukraine, innovative developments for radioactive waste management should be implemented, methods of wastewater treatment must be developed/improved, prevention and elimination of natural and emergency emergencies should be provided. It is important to create variety of scientific, technical and innovative developments to solve these problems. Their development is carried out by institutions and organizations, including the National Academy of Sciences of Ukraine. The study analyzes and summarizes activities of the State Institution “The Institute of Environmental Geochemistry of National Academy of Sciences of Ukraine” on innovative developments to improve nuclear, radiation and technogenic environmental safety. The developments of the Institute are defined, described and systematized. The performed research was aimed to solve problems of sustainable development of nuclear energy, environmental problems of nuclear fuel cycle, handling of radioactive materials at all stages of their life cycle.

“…When radiation fields are considered, special attention is paid to the development of procedures for identifying the array of detector's readings [8,9,14,15]. The choice and details of the implementation of such procedures depend on the problem's specifics, but, as a rule, they are based on the statistical nature of the signals being recorded.…”

The use of radioactive materials is widespread in scientific investigations and various sectors of the economy. There are also extremely radiation-hazardous objects, for instance the well-known Chornobyl Exclusion Zone (Chornobyl, Ukraine) covering the large contaminated areas and the Shelter Object containing the materials of huge radioactivity of about 20 MCi. To safe handling with such objects and materials, the correct their monitoring, detection and characteristics evaluation are vital. The modern development of small flying machines, measurement equipment, and information technologies allow one to increase the amount of measurement data and their accuracy, and to reduce the processing time. On the other hand, the requirements to accuracy, quickness, and correctness of data interpretation increase as well. To solve these problems effectively, the mathematical tools of data processing should be improved. The main mathematical problem at the remote evaluation of radioactive fields relates to the solving the inverse problem for the Fredholm integral of the first kind. In this research, we consider the reconstruction of surface density of gamma radiation on the ground using the data of aerial shooting. We survey the methods for solving the inverse problem, their advantages and disadvantages. The adaptation of the methods to the reconstruction of nonstationary discontinuous radioactive fields is presented. We modify the numerical algorithms using the opportunities of modern calculating software. In particular, it is considered the task when the algorithm reconstructs the density distribution very well.
