Contribution of foodstuffs contained radionuclides to formation of internal radiation doses received in areas Bryansk region affected by the Chernobyl accident

The authors review current specific features of internal radiation doses received by people resided in 135 urban and rural settlements six south-western districts the Bryansk region affected Chernobyl accident. residents average annual dose > 1 mSv. Cs-137 radioactivity contained local agricultural natural food was evaluated with account dietary structure. Comparative analysis long-term data on a contribution radionuclides to population, estimated effective carried out. Potatoes pork taken from private farms under survey met health hygiene standards for different levels 2022. However, there risk exceeding sanitary hygiene’s requirements milk privately-owned located 89% survey, 98% beef produced 100% mushrooms collected forests near these settlements. Currently, main dose-forming product is (contribution exposure 60%), smaller role formation (about 20%) minimal potatoes meat (10% each). Over past 20 years, has increased 15-20%, decreased because changes diet population due reduction redistribution products basket.
