Measurement of radioactivity in the environment. Air: radon-222 - Integrated measurement method for determining average potential alpha energy concentration of its short-lived decay products1 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

as well as within the lifecycle steps and processes of health software development

This will assist in reconciling the often-conflicting management and maintenance requirements of water and wetland areas
