Your Radon detector can remain on permanently without risk. However, in order to turn it off
during a long period of inactivity, press and hold the button until the LED turns green
(approximately 10 seconds). To turn it back on, press and hold the button again for a few seconds.

Radon measurement is e pressed in a unit called “Becquerel per cubic meter” (Bq/m³) and is
called “Radon activity concentration”.

● FREQUENTLY ASKED QUESTIONS
Why my Radon sensor always dis lays the same values ?
How to get a more accurate measurement ?
To fully understand the importance of the duration of the measurement, imagine a survey
carried out on a random sample of people : A survey carried out on 1000 people is necessarily much
more accurate than a survey carried out on only 10 people. Similarly, a Radon measurement taken
over 24 hours is much more accurate than a Radon measurement taken over 1 hour.
