The Institute of Radiobiology offers consumers services in developing recommendations for the use of complex mineral supplements based on phosphogypsum in feeding lactating cows kept in areas of radioactive contamination under an outsourcing agreement and is looking for partners to conclude a distribution services agreement.

The recommendations analyze the provision of typical rations of lactating cows kept on agricultural enterprises located in radionuclide-contaminated areas of the Gomel region with macro- and microelements. Compositions of mineral feed additives with the inclusion of phosphogypsum for lactating cows have been developed.

The recommendations have been prepared based on the results of studies carried out within the framework of the State Program for Overcoming the Consequences of the Chernobyl Disaster for 2011–2015 and for the Period up to 2020, and have no analogues.

The scope of application is regional and district management structures of the agro-industrial complex located in radionuclide-contaminated areas, organizers of private subsidiary (farm) households, employees of scientific institutions, teachers, students and pupils of educational institutions of the zoo-veterinary profile.

Information is posted in the "Album of Promising Developments of Organizations of the National Academy of Sciences of Belarus for the Real Sector of the Economy" (2023), pp. 361-362. (in Russian)

The recommendations are presented on paper and interactively as an information application (web application) and are available on the Internet for free use.
It is possible to develop targeted formulations of complex mineral supplements based on phosphogypsum and other local sources of mineral raw materials (tripoli, sapropel) in order to eliminate the deficiency of macro- and microelements in the diets of lactating cows kept in the territory of radioactive contamination.
The information application on the Internet was viewed by users from the Republic of Belarus, the Russian Federation, and Kazakhstan.
The use of recommendations allows for a reduction in the dose of internal radiation due to the consumption of milk with a minimum content of radionuclides, optimization of the mineral composition of cows' diets, and an increase in milk productivity by 5–8%.
Practical implementation of the measures developed in the recommendations ensures the production of environmentally safe milk that meets the regulatory requirements for the content of radionuclides RDU-99 and TR CU – 021/2011.
Based on the calculations of the average weighted values ​​of the actual mineral nutritional value of herbaceous forages, a deficiency of mineral substances in the diets of lactating cows kept in specific agricultural enterprises of the Gomel region with problems in obtaining milk that meets the requirements of RDU-99 for the content of ⁹⁰Sr (3.7 Bq) is established. Based on the analysis of the level of provision of lactating cow diets with macro- and microelements, targeted compositions of mineral supplements are calculated based on local sources of mineral raw materials in the following options: based on phosphogypsum; phosphogypsum-tripoli; phosphogypsum-sapropel; phosphogypsum-tripoli-sapropel. These feed additives can be fed both in free form and as part of compound feed.

The State Scientific Institution "Institute of Radiobiology of the National Academy of Sciences of Belarus" is a leading organization carrying out scientific and scientific-organizational activities in accordance with the main areas of scientific research:

– assessment and forecast of long-term medical and biological consequences of the action of ionizing radiation;
– study of the combined effect of radiation and non-radiation factors on the body, including electromagnetic radiation, development of protective measures;
– assessment of the impact of radioactive contamination on the environment, plants, and animals, development of methods for safe environmental management, radioecological monitoring;
– study of the processes of inclusion of radionuclides in food chains under conditions of radioactive contamination, including transuranium elements, their intake and accumulation in the body and the formation of radiation doses, development of methods for influencing these processes in order to reduce negative consequences.

The priority areas of scientific and technical activity and fundamental and applied scientific research are:

- Medicine and Pharmacy: the creation of new technologies for the prevention of diseases based on the use of biologically active additives and other medicines;
- Ecology and rational nature management: monitoring and forecasting the state of the environment, rehabilitation of radioactively contaminated lands;
- Development of new therapeutic, diagnostic, preventive and rehabilitation technologies, medical devices and products, medicinal and immunobiological preparations, cellular and molecular biological technologies: mechanisms of adaptation of the human body to the action of environmental factors, including the effects of ionizing radiation;
– “Ecological safety, environmental protection, minerals and subsoil of Belarus, efficient use and renewal of natural resources, prevention and elimination of consequences of emergency situations”: protective measures to overcome the remote radioecological consequences of the Chernobyl disaster.
- study of the mechanisms of the biological action of low doses of ionizing and non-ionizing radiation and the influence that has developed in the regions of the republic, the environmental situation on living organisms;
- study of patterns of behavior of pollutants and radionuclides in ecosystems, their inclusion in trophic chains and accumulation in the body;
- development of ways and means to reduce the negative impact of environmental factors on human health.

International cooperation agreements are being implemented with specialized organizations of the Republic of Azerbaijan, the State of Japan, the People's Republic of China, the Kingdom of Sweden, the Republic of Lithuania, the Republic of India, the Republic of Kazakhstan, the Republic of Korea, the Republic of Poland, the Republic of Serbia, the Russian Federation, Ukraine, the Federal Republic of Germany, the French Republic , Czech Republic.
