Radon is a natural radioactive gas from the decay of uranium, a naturally occurring element in soil and rocks. It easily escapes from the soil and accumulates in dwellings and buildings. The progeny from radon decay is radioactive and becomes attached to dust and particulate in the air: when inhaled, this radioactive particulate settles in the lung and over time can cause lung cancer. Radon is the second leading cause of lung cancer after smoking.
At CERN, we have prototyped an innovative radon monitoring device RaDoM and developed a cloud based service to collect and analyse the data, to control the measurements and to drive mitigation measures based on real time data.
