The ISO 18589-6 standard specifies a test method for the measurement of total alpha and total beta radioactivity in soil, using Gas-flow Proportional Counting. This method assesses the level of radioactive contamination of soil by measuring the alpha and beta rays of radioactive particles in soil samples. Gas-flow Proportional Counting is a commonly used technique for measuring radioactive activity with high-precision and Sensitivity. The standard provides reliable technical support for environment monitoring and is suitable for the detection and evaluation of radioactive substances in soil. It has important application value especially in the field of environment protection and public health.
