Measurement of radioactivity in the environment. Air: radon-222 - Integrated measurement method for determining average potential alpha energy concentration of its short-lived decay products Ingestion-build-183511 Fixed film treatment1 Scope This document describes integrated measurement methods for short lived radon222 decay products[4]. It gives indications for measuring the average potential alpha energy concentration of shortlived radon 222 decay products in the air and the conditions of use for the measuring devices. This document covers samples taken over periods varying from a few weeks to one year. This document is not applicable to systems with a maximum sampling duration
