Abstract

After any nuclear disaster, radioactive materials are released into the environment, polluting the environment, livestock and livestock products. These substances can enter the human body in the natural cycle through the food chain, a process which must be avoided. To this end, in this study, while examining the release of nuclear materials and the contamination of farm animals and livestock products after nuclear accidents in the world, especially the Chernobyl (1986) and Fukushima (2011) disasters, the ways to prevent or eliminate the induced contaminations were also examined. Due to the importance of 3 radionuclides; radio-cesium, radio-iodine and     radio- strontium, their cycles in nature were studied. This is a qualitative study based on retrospective time dimension with an applied purpose. Results of this study demonstrated that after exposure to radioactive substances animals have shown side effects such as immune deficiency, lowered body temperature, heart failure, partial atrophy or complete destruction of the thyroid gland, liver damage and eventually death. In the event of a nuclear disaster, it is essential that effective measures be taken as soon as possible to reduce the transmission of radioactive contamination to the food chain. Radiological monitoring of livestock products, prohibition of the use of contaminated food in livestock and poultry feed, and processing of food prepared from livestock products, are among the defense methods that can be used to reduce the transfer of radioactive materials from livestock products to humans. The results of this study also indicated that, exploration of radionuclide transport pathways to farm animals and their products can lead to the design of countermeasures that have the highest degree of efficacy and can be implemented in the shortest possible time to avoid maximum contamination.
