Abstract

This paper presents research on the assessment of the radioecological state of plant cover surrounding two research reactor facilities located within the Semipalatinsk Test Site (STS) as examples of nuclear fuel cycle facilities (NFC). Source data on the concentrations of artificial radionuclides in the plant cover were obtained. Quantitative values for 137Cs, 241Am, and 239+240Pu activity concentrations were determined in plants across the perimeters of the facilities, indicating that these compounds may be present in the associated media from the perspective of accumulative bioindication. The values determined for artificial radionuclides in the \'soil‒plant\' system around the researched NFC facilities were attributed to radioactive contamination of the STS territory.

摘要

本文介绍了有关评估位于塞米巴拉金斯克试验场（STS）内的两个研究反应堆设施周围的植物覆盖物的放射生态状态的研究，以核燃料循环设施（NFC）为例。获得了有关植物覆盖物中人工放射性核素浓度的源数据。137Cs的定量值，241Am,并在设施周边的植物中确定了239+240Pu的活性浓度，这表明从积累的生物适应症的角度来看，这些化合物可能存在于相关的培养基中。在所研究的NFC设施周围的“土壤植物”系统中确定的人工放射性核素值归因于STS领土的放射性污染。
