The Radtrak2 device is analysed by an accredited laboratory in Chicago.
Accreditation guarantees the quality of a radon measurement, in part because the laboratory’s measurement processes are regularly checked by independent organizations. However, most of the world’s radon laboratories are not accredited, which to many might seem a little strange. Why is this? Firstly, accreditation entails a large additional cost and secondly customers do not demand it, but this is expected to change.
The definition of an accredited radon measurement is a measurement obtained using radon detectors from a laboratory which is accredited according to ISO/IEC 17025 and follows the instructions that accompany the detectors.
