Monitoring of radionuclide contamination of plants in the western part of Volyn Polissya (Ukraine) during 1994–2007

Abstract: Abstract. We present the main results of our more than decade-long monitoring of 137 Cs content in berry plants and medical herbs growing in the Shatsk National Natural Park (Volyn Region, Ukraine). It is shown that the 137 Cs content for most of the medical herbs has significantly decreased during the monitoring time period and now it meets the demands of Ukrainian sanitary standards (less than 200 Bq/kg d. w.). The decreasing rate is much higher than that for the corresponding soils. This is because the radi… Show more

“…• Need for K+, 2 Ca+ and other cations 137 Cs and 90 Sr are not the only radionuclides left in soils after Chornobyl disaster, yet being the most dangerous. The major danger is caused by their feature of substituting the vital minerals: 137 Cs is perceived as K, and 90 Sr as 2 Ca. The plants literally mistake the radionuclides for these cations and get contaminated.…”
