Критерии и операционные дозиметрические величины для проведения защитных и неотложных медико-санитарных мероприятий в начальном периоде радиационной аварии

The article deals with the criteria of radiation hazard and the relevant values of operational dosimetric quantities in order to preliminary assessment of the consequences and to make recommendations for the protective and urgent medical-sanitary actions in case of the radiological emergency. The article describes a scenario where, in the absence of information about the parameters of radioactive release or radioactive source, initial assessment of radiation consequences is developed based on the first dosimetry measurements in the environment.
