CRITERIA FOR THE PROTECTION OF POPULATION AFTER RADIATION ACCIDENT: FOOD CONSUMPTION STRUCTURE AND PECULIARITIES OF THE INTERNAL DOSES FORMATION OF VARIOUS AGE GROUPS OF THE POPULATION OF THE RUSSIAN FEDERATION

Abstract

The aim of the work is to assess the compliance of the possible doses to the population of the Russian Federation, calculated on the basis of current data on the levels of food consumption with the activity concentration corresponding to the intervention «A», according to NRB-99/2009, the dose criteria for making decisions on limiting food consumption. Estimates are made for the situation of contamination of the main food products (milk, potatoes, vegetables, meat, fruits and fish) with the cesium-137 and strontium-90 activity concentration of 1000 Bq / kg and 100 Bq / kg, respectively. It is shown that, taking into account the current data on the levels of consumption of various food products, the calculated doses for all age groups of the population do not exceed the NRB-99/2009 dose criterion of 5 mSv with the consumption of any of the listed foods within the first year after the accident, as for cesium-137, and for strontium-90. The results obtained can be used to justify the temporary permissible levels of the cesium-137 and strontium-90 contamination of one or more food products.
