Measurement of radioactivity in the environment. Air: radon-222 - Spot measurement methods of the activity concentration not-eligible it specifies the tests1 Scope This document describes radon 222 spot measurement methods. It gives indications for carrying out spot measurements, at the scale of a few minutes at a given place, of the radon activity concentration in open and confined atmospheres. This measurement method is intended for rapid assessment of the radon activity concentration in the air. The result cannot be extrapolated to an annual estimate of the radon activity concentration. This type of
