This part of IEC 61577 describes the specific requirements for instruments measuring the exposure to airborne radon (²²²Rn) outdoors and indoors. The exposure is the time-integrated radon activity concentration in air accumulated over the exposure period.

This document applies to radon integration measurement systems equipped with solid-state nuclear track detectors (SSNTD) installed in an enclosed volume. The air containing ²²²Rn enters the volume by diffusion.
