Abstract
Granite territories continuously release radon, a radioactive gas that can be very harmful to human health. The assessment of radon gas indoor concentration is relevant for granitic buildings that lie over this substrate. In this work we use a sensor system to study the variation through time of indoor air quality (IAQ) parameters like radon concentration, temperature, and humidity following the occupation pattern of a school building made of granite. We identify distinctive radon concentration patterns that can be related with the time of day and week days that result from human occupation of the building and establish a basic indicator for radon exposure risk. The results of this analysis identify critical periods during the day that should be the subject of future mitigation strategies through an actuator system in order to improve the IAQ.
