CLASSIFICATION OF MEDICAL EQUIPMENT FOR ANTI-RADIATION PROTECTION.

Any collection of objects of study needs some arrangement, i. e. classification. The existing numerous classifications of antiradiation agents are built on the basis of their antiradiation effects of an integrated or differentiated nature. The work presents the chronology of the main classifications of chemical compounds that are able to protect against the shortterm and longterm effects of ionizing radiation when they are introduced into the body both before and after exposure. The change of views, trends and paradigms regarding radioprotective compounds is shown. These classifications of antiradiation medicines include radioprotectors, means of stimulating the radioresistance of the body, means of prevention and suppression of the primary reaction to irradiation, means of prevention and treatment of lesions from exposure to incorporated radionuclides, means of treatment of acute bone marrow syndrome, means of treatment of local radiation lesions. It is shown that modern concepts of radiation protection are based on fundamentally different «points of application» of groups of radioprotective agents and depend on the stage of radiation damage.
