Selection of the right location for exposure and installation
The instrument should be placed at a location which is representative for the indoor air quality of a
room. The incidence of direct light and exposure to strong heat sources should be avoided. For
permanent installation, the Smart Radon Sensor can be mounted on a wall using a wall mounting clip
(accessory). Attention has to be paid because the wall itself could be the origin of the Radon inside a
room. This would result in an increased concentration in the surrounding of the surface. Some
comparison measurements at the preferred mounting position and in the middle of the room (each
at least a few days under similar weather conditions) will show if this is the case or not.
When the mounting of the device is accomplished the terminal block can be wired. If the batteries
were replaced before the installation had taken place, the internal clock has to be set with Radon
Vision software over USB connection.

Selection of the right integration interval
It is possible to adjust the sampling interval of the Smart Radon Sensor between 1 and 255 minutes.
From the physical point of view it makes no sense to choose intervals shorter than 30 minutes
because the response time of the instrument is in that order. If the expected Radon concentrations
are in the range or less than the statutory reference level of 300Bq/m³, an interval of 60 minutes
(default setting) should be used. Frequent zero readings for individual sampling intervals indicate
that the chosen interval is too short.
