Measurement of radioactivity in the environment. Air: radon-222 - Origins of radon and its short-lived decay products and associated measurement methods Ingestion-build-189776 What is BS EN 616851 Scope This document outlines guidance for measuring radon 222 activity concentration and the potential alpha energy concentration of its short lived decay products in the air. The measurement methods fall into three categories: a) spot measurement methods; b) continuous measurement methods; c) integrated measurement methods. This document provides several methods commonly used for measuring radon 222 and its short lived decay products in air. This
