摘要

氚（3H）仍然是一种重要的放射性核素，在塞米巴拉金斯克试验场（STS）的所有环境单元中都检测到大量的放射性核素。本研究提供的数据描述了放射性污染的STS地点- Degelen站点的影响区域的3H旅行水平。水、土壤、沉积物、空气和萤石矿石（Karadzhanly矿床产品）3H活性浓度（包括物种）使用液体闪烁光谱设备“TRI-CARB 2900 TR”（PerkinElmer， USA）进行测量。植物样品使用“QUANTULUS 1220”（PerkinElmer， USA）进行测量。植物样品使用“QUANTULUS 1220”（PerkinElmer， USA）进行测量。植物游离水3H （TFWT）最高可达41 kBq/kg，土壤和底泥（TSAW）最高可达29和26 kBq/kg。3H进入环境组分的主要来源是地下水，最高可达78 kBq/kg。在Karadzhally萤石矿床作业期间，3H对人员的年有效内剂量不超过标准。

Tritium distribution in environmental compartments of the impact zone of radioactively contaminated areas

Tritium (³H) remains a prominent radionuclide detected in notable quantities in all environmental compartments of the Semipalatinsk Test Site (STS). This study presents data describing the levels of ³H travel in areas of the impact zones of radioactively contaminated STS locations — the Degelen site. Water, soil, sediments, air, and fluorite ore (Karadzhanly deposit product) ³H activity concentrations (including the speciation) were measured using liquid scintillation with spectrometric equipment “TRI-CARB 2900 TR” (PerkinElmer, USA). Plant samples were measured using “QUANTULUS 1220” (PerkinElmer, USA). Plant samples were measured using “QUANTULUS 1220” (PerkinElmer, USA). The high values were set in free water ³H in plants (TFWT) – up to 41 kBq/kg, in soils and bottom sediments (TSAW) – 29 and 26 kBq/kg, respectively. The main source of ³H entering the environmental components is groundwater – up to 78 kBq/kg. Annual effective internal dose from ³H to personnel during operations at the Karadzhally fluorite deposit does not exceed Standards.

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
