ISO 18589-6:2019标准是ISO 18589系列标准的一部分，该系列标准主要涉及环境放射性测量。该标准主要针对土壤中总α和总β活度的测量方法，采用气流比计数法进行测量。该标准适用于土壤样品的测量，包括表层土壤、深层土壤和污染土壤等。

该标准要求在测量前对土壤样品进行处理，以确保测量结果的准确性和可靠性。处理过程包括样品的干燥、研磨和筛分等步骤。在测量过程中，需要使用气流比计数器进行测量，该计数器能够同时测量总α和总β活度。测量结果需要进行校正，以消除仪器本底和样品自身的贡献。

该标准还规定了测量结果的报告要求，包括测量结果的单位、测量不确定度、仪器本底和样品自身的贡献等。同时，该标准还提供了一些参考值，以帮助评估土壤中的放射性污染程度。

总之，ISO 18589-6:2019标准提供了一种可靠、准确、可重复的土壤总α和总β活度测量方法，为评估土壤中的放射性污染程度提供了重要的技术支持。
