Abstract

Soil remediation at nuclear sites is necessary to protect ecosystems and public health. The design of remediation includes an appropriate measurement strategy to reduce economic and environmental costs. Field measurements of soils containing natural U are challenging due to the low energy and intensity of ²³⁸U daughter gamma emissions. Due to self-absorption at the source, the detection of the ^234mPa beta emission requires the establishment of an adequate thickness, making it difficult to measure in the field.

This paper describes the design of an automated measurement system for the in situ measurement soils contaminated with uranium. The system allows the radiological classification of soils according to their level of compliance with the criterion of unrestricted release of the site. Its use has the advantage of providing results faster and at a lower cost than laboratory sampling. The result is a real optimisation of radioactive waste management.

铀污染土壤修复中废物管理的优化

核设施的土壤修复对于保护生态系统和公众健康是必要的。补救措施的设计包括适当的测量策略，以减少经济和环境成本。由于238U子γ辐射的低能量和强度，对含有天然U的土壤进行现场测量具有挑战性。由于在源处的自吸收，检测234mPa的β发射需要建立足够的厚度，这使得在现场测量变得困难。本文介绍了一种用于铀污染土壤原位测量的自动化测量系统的设计。该系统允许根据土壤符合场地无限制释放标准的程度对土壤进行放射学分类。它的优点是比实验室取样更快、成本更低。其结果是放射性废物管理的真正优化。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
