Radiation pathology of the thyroid gland lecture 2. Iodine blockade in accidents at nuclear production

Currently, more than 400 nuclear power plants (NPPs) are operating on the planet, more than 100 are under construction. In addition, a large number of individual nuclear reactors operate. By 1990, 46 power units at 15 nuclear power plants were operating in the territory of the former USSR, 111 reactors in the United States and another 12 are under construction. Hundreds of tons of uranium oxide are loaded into nuclear reactors. Therefore, during the generation of atomic energy, they accumulate a huge amount of radioactive substances (RS), formed during the physical decay of the nuclei of fuel atoms. Reactors are primarily a potential source of radiation hazard and the release of radioactive substances contained in them into the environment and the human body.
