Measurement of radioactivity in the environment. Air: radon-222 - Spot measurement method of the potential alpha energy concentration of its short-lived decay products Ingestion-build-83346 Digital signature mechanisms can be1 Scope This document describes spot measurement methods for determining the activity concentration of short lived radon 222 decay products in the air and for calculating the potential alpha energy concentration. This document gives indications for performing a spot measurement of the potential alpha energy concentration, after sampling at a given place for several minutes, and the conditions of use for the measuring devices. The measurement method
