Abstract: Recent data on radionuclide contents of Chernobyl origin in food products and drinking water for the Belarusian population are reviewed. Strontium-90 and Cesium-137 are main radionuclides contributing to internal irradiation to the population. Contamination levels in food products from the social sector of agriculture (collective farms, agricultural co-operatives) are found to be generally below the current legal admissible level of RAL-99 that are defined to make internal dose of the population less than 1 mSv/yr. On the other hand, exceedings of RAL-99 are often found in food products from the private sector, especially in settlements of Gomel region where the contamination is the most serious in Belarus. Special attention should be paid to the non-farm products in the contaminated areas: mushrooms, berries, fish and meat of wild animals. For example, about 37,000 Bq/kg of 137Cs in fresh mushroom was registered in a settlement of Gomel region, which corresponds to 100 times of RAL-99 values. Concerning drinking water, the situation is quite good and no execeedings have been registered for the last 10 years.
