CONTENT OF 137CS AND 90SR IN THE MEDICINAL AND OTHER ECONOMICALLY VALUABLE PLANT SPECIES FROM THE KORMYANSKY DISTRICT OF THE GOMEL REGION OF THE BELARUS REPUBLIC EDUCATIONAL ORGANIZATION «GOMEL STATE UNIVERSITY AFTER F. SKORINA»

Abstract

Investigation results of the contamination with 137Cs and 90Sr of the plants from natural ecosystems of four objects are being presented. 45 plant samples and 24 soil samples were analyzed. It was revealed that the permissible level for the 137Cs content of 370 Bq/kg, is exceeded for 21 samples (46.7 %). Content of 90Sr in plants varied from 3 Bq/kg to 544 Bq/kg. Most part of the radionuclides still remains in the upper soil horizons. Plant species specificity concerning the radionuclide accumulation depends on the composition of the natural ecosystem, type of soil, its agrochemical composition and humidity.
