Measurement of radioactivity in the environment. Soil - Gross alpha and gross beta activities. Test method using gas-flow proportional counting1 Scope This document provides a method that allows an estimation of gross radioactivity of alpha and beta emitters present in soil samples. It 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 or radioactivity is generally different
