Health Canada Guide for Radon Measurements in Public Buildings (Schools, Hospitals, Care Facilities, Detention Centers)

 This document is intended for persons or organizations proposing to carry out radon measurements in public buildings. These buildings, considered dwellings, have a high occupancy rate and/or residency period for members of the public. The types of buildings include hospitals, schools, long-term care residences and correctional facilities. The purpose of testing for radon is to evaluate the levels in order to determine whether remedial action is required to protect the dwelling residents. Occupational exposure of workers to radon is addressed separately through existing guidelines or regulations such as the Canadian Guidelines for Management of Naturally Occurring Radioactive Materials (NORM) and the Canada Labour Code. The scope of this document is limited to guidance regarding types of measurement devices, device placement, measurement duration, and the interpretation of measurement results regarding corrective action for health protection in public buildings and schools.
