In assessment was performed for critical group living territory contaminated with radionuclides; working studying at school located on former site. annual dose burden is 2.5 mSv y−1 Zavodskoy, 1.9 Kvartsitka 3.6 Aqsu; from radon around 11 ground floor, teachers - up 12 mSv*y−1. At settlements, however, under hypothesis that all food radionuclides vegetables cultivated locally territories high background level, ingestion 9.1 8.3 11.5 Aqsu. combined effects problems culminated into problems. There are such possibility higher prevalence cardiovascular, digestive respiratory systems so it necessary or protect people area.
