[Methodological principles for using agents for the mass prevention of the sequelae of human irradiation]

The means of mass prevention of radiation consequences are biologically active additives to food, usual diet components, etc., micronutrients, as well as some sorbents and radio protective agents, which show various actions: 1) those reducing absorption; 2) those accelerating radionuclide excretion; 3) those enhancing the body's resistance to radiation; 4) those contributing to the prevention (less risk) of late radiation-induced cancer. The paper formulates basic requirements for means of mass prevention and guidelines for their use in terms of benefits and risk.
