Matvienko D. Radiological research and quality assessment methodology of measurements of food products

It was developed on the introduction of a new method of radiochemical analysis of food products on the content of radionuclides using bioindicators, which increased the accuracy of measurements, which in turn influenced the quality of products. The method of collecting and processing and effective use of technical and economic information, systematization, complex estimation, forecasting and control of the influence of technogenic loads on compliance with Ukrainian standards has been developed. A specialized computer system was developed for the collection, analysis and visual interpretation of medical-radiological and food monitoring data, including a database, means of graphic representation of information, software for environmental protection tasks and cartographic modeling of technogenic pollution. The complex analysis of monitoring data in the districts of Cherkassy region was carried out with the help of developed algorithmic and software tools, polluted areas were zoned according to radiological indices, correlation dependencies between levels of pollution and disease in separate regions were investigated to protect consumers' interests, to ensure the quality of export of products of the region, , human health, environmental protection. In the software environment, MATLAB 7 is modeled in the dialog mode and presents in graphical form the dynamics of 90Sr and 137Cs transfer processes and the formation of effective equivalent doses for different age groups of the population of Cherkasy region. According to the statistical data of the radiation pollution of the Cherkasy region effective equivalent doses for different age categories of a person are calculated on a time interval of 1 month and 1 year.
