Abstract

A specific goal of the French army is to ensure health protection of soldiers consuming water from overseas operations territories. To do so, the French Defence Radiological Protection Service developed a method to quantify the amount of ²²⁶Ra in water using Ra-Nucfilm discs. ²²⁶Ra analysis is achieved within less than two days and the detection limit, function of adsorption efficiency, ranges from 0.85 to 25 mBq/L. The novelty is the determination of a factor correcting adsorption efficiency, equal to 1.3, from the difference in adsorption between ²²⁶Ra and ¹³³Ba using as internal tracer.

ra -核膜圆盘法测定饮用水中226Ra的吸附效率修正。

法国军队的一个具体目标是确保从海外行动领土饮水的士兵的健康保护。为此，法国国防辐射防护服务部门开发了一种方法，使用Ra-Nucfilm光盘来量化水中226Ra的含量。226Ra分析在不到两天的时间内完成，检测限（吸附效率函数）范围为0.85至25 mBq/L。新颖之处在于，利用内部示踪剂226Ra和133Ba的吸附差异，确定了一个校正吸附效率的因子，该因子等于1.3。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
