摘要

本文介绍了一种基于二氧化碳和液体闪烁计数的放射性碳测年系统的发展。该系统具有足够的灵活性，可以应用于不同的领域，如放射性碳测年(跨度可达约32000年)、环境放射性监测和确定环境生态安全的可生物降解和生物合成产品中生物碳的比例，并有助于对习俗进行认证。实施的系统是按照标准方法(ASTM D6866-06)开发的。它已经过校准、测试和验证，用于二氧化碳的产生、吸收和计数(使用适用于当今、化石和不同时代的适当参考材料)。这些结果令人乐观，开发的系统可以为正在进行和即将进行的环境友好型产品的认证做出贡献。

Development of direct CO2 absorption system for radiocarbon dating and bio-based carbon determination in biogenic-synthetic products

This work presents a development of a new radiocarbon dating system based on CO2 and liquid scintillation counting. The system is flexible enough to be applied in different fields such as radiocarbon dating (up to about 32 000 years span), environmental radioactive monitoring, and determining the fraction of biological carbon in environmentally-ecologically safe biodegradable and bio-synthetic products, and help accreditation to customaries. The implemented system is developed following the standard method (ASTM D6866-06). It has been calibrated tested and verified for CO2 production, absorption, and counting (using appropriate reference materials for the present-day, fossil, and in between ages). These results are optimistic that the developed system can contribute to the accreditation of ongoing and upcoming environment- friendly productions.

期刊介绍： Nuclear Technology & Radiation Protection is an international scientific journal covering the wide range of disciplines involved in nuclear science and technology as well as in the field of radiation protection. The journal is open for scientific papers, short papers, review articles, and technical papers dealing with nuclear power, research reactors, accelerators, nuclear materials, waste management, radiation measurements, and environmental problems. However, basic reactor physics and design, particle and radiation transport theory, and development of numerical methods and codes will also be important aspects of the editorial policy.
