This article presents the results of radiocarbon distribution in natural components of 'Degelen' test location. It was used to conduct underground nuclear tests at the Semipalatinsk Test Site. Near-entry areas with water inflows were selected for research. Soil, plant and water samples were taken, in which the radiocarbon content was determined. The 14С activity concentration was determined using a highly sensitive alpha-beta radiometer SL-300 (ISO 13162, 2021). Sample preparation was carried out using a modern automated system Pyrolyser-6 Trio (Raddec International Ltd, UK). In the course of research undertaken, radiocarbon was revealed to be nonuniformly distributed in environmental objects. The effectiveness of Pyrolyser-6 Trio calcination and ashing system for 14C determination in environmental matrices has been demonstrated.
本文介绍了“杰格连”试验场自然组分中放射性碳分布的结果。该试验场曾用于在塞米巴拉金斯克试验场进行地下核试验。选择有水流流入的近入口区域进行研究。采集了土壤、植物和水样，并测定了其中的放射性碳含量。使用高灵敏度的α-β辐射计SL-300（ISO 13162，2021）测定了14С活度浓度。样品制备使用现代自动化系统Pyrolyser-6 Trio（英国Raddec International Ltd公司）进行。在研究过程中，发现放射性碳在环境物体中的分布不均匀。已证明Pyrolyser-6 Trio煅烧和灰化系统在环境基质中测定14C的有效性。
