Radioactive iodine is present in atmospheric fallout during the first hours of accidental emissions at nuclear power plants. It causes damage to the thyroid gland of varying severity. As a result of lesions with radioactive iodine, pathological changes develop in the thyroid gland, which can affect the productive indicators and reproduction of farm animals. Physiological changes are also diagnosed in animals that do not receive a sufficient amount of iodine compound with food or water. This can lead to pathology of the thyroid gland. Studies of the pathology of the thyroid gland should be carried out on the basis of structural modeling methods and data obtained experimentally. Analysis of the comparison of pathological effects allows to systematize information and use it in scientific and practical purposes. Depending on the intensity and duration of external and internal radiation exposure in farm animals acute or chronic radiation diseases can be diagnosed. Farm animals with or without signs of radiation disease of mild severity are left in farms and used for its intended purpose. Long-term effects of radiation can be manifested as temporary or permanent sterility, metabolic and endocrine status disorders, immunodeficiency, increased sensitivity to infectious diseases, the emergence of tumors. Monitoring of the radiological situation on the territory of the livestock complex is of particular importance, as its products are transported to different regions. Livestock products must meet regulatory requirements. Timely and full implementation of general and specific rules in the field of radiation safety is aimed at ensuring the safety of animals and preserving the quality of animal products.
