The Expert Group Actions Algorithms of the Emergency Medical Radiation Dosimetry Center in Various Scenarios of Radiation Accidents

Purpose: Consideration of experts group algorithms for assessing the radiation situation and its health care consequences during various types of radiation emergencies used in Emergency Medical Radiation Dosimetry Center (EMRDC) of A.I. Burnasyan Federal Medical Biophysical Center.

Material and methods: The algorithms include a set of methods and models, the use of which allows for a preliminary predictive assessment for making decisions on the implementation of protective and health care actions.

Results: Based on the analysis and systematization of 25 years of experience, the algorithms for the work of the EMRDC expert group during radiation incidents and during emergency exercises and training are presented. The presented algorithms reflect the sequence of expert assessments, starting from the parameters of the hazard source and the conditions of dose formation, and ending with the preparation of recommendations for protective measures and determination of the class of radiation accident according to the International Nuclear Safety Scale (INES). As a rule, conducting preliminary calculations in a short time frame is associated with uncertainties in the results of assessments at each stage of forecasting. At the same time, the objectivity of assessing the consequences of a radiation incident is increased by using data from direct dosimetric measurements or the results of clinical-dosimetric examination of victims.
