标准范围

ISO 18589-6:2009提供了一种方法，可以估算土壤样本中存在的α和β辐射源的总放射性。ISO 18589-6:2009基本上适用于基于比较测量的系统检查或初步现场研究，以指导测试人员优先选择土壤样品进行测量，以及具体分析方法的实施。总a或β放射性通常不同于现有放射性核素的有效放射性之和，因为按照惯例，所有α排放都指定了相同的α计数效率，所有β排放都指定了相同的β计数效率

ISO 18589-6:2009 provides a method that allows an estimation of gross radioactivity of alpha- and beta-emitters present in soil samples. ISO 18589-6:2009 applies, essentially, to systematic inspections based on comparative measurements or to preliminary site studies to guide the testing staff both in the choice of soil samples for measurement as a priority and in the specific analysis methods for implementation.The gross a or β radioactivity is generally different from the sum of the effective radioactivities of the radionuclides present since, by convention, the same alpha counting efficiency is assigned for all the alpha emissions and the same beta counting efficiency is assigned for all the beta emissions
