Sources and transport of indoor radon. Measurements and mechanisms

摘要

An approach in the investigation was to use a multi-compartment model of a home describing the processes that determine how radon concentrations in dwellings are established. Because the model describes Rn-222 concentrations in terms of airflows and sources, the experimental research was focused on the measurement of these three quantities. Development, calibration and assessment of the instrumentation played a major role. The experiments involved measurements of Rn-222 exhalation of buildings materials and the soil underneath the house, Rn-222 concentrations in air and airflows between various parts of the house and between the inside and outside of the house.
