“…In Belgium, about 10,000 houses were surveyed, and the results showed the highest indoor radon levels on sandstone, quartz-phyllite, psammite, and greywacke; moderate levels on phyllite, mica-sandstone, limestone, chalk, and calc-shale; and lowest levels on sand, clay and marl [147]. Elevated indoor levels of radon and thoron are also expected in buildings on volcanic ground and made of volcanic material, as seen from the studies in Italy and Spain [148][149][150]. Also, in Hungary, the highest indoor radon activity concentrations in 6154 one-storey, no-basement houses were found on Cenozoic volcanic rocks, followed by Paleozoic granites, with the lowest in houses constructed on sedimentary fluvial and partly Aeolian formations [151].…”

Initially, basic equations are given to express the activity concentrations and concentrations of potential α-energies of radon (222Rn) and thoron (220Tn) and their short-lived products in indoor air. The appearance of short-lived products as a radioactive aerosol is shown, and the fraction of the unattached products is particularly exposed, a key datum in radon dosimetry. This fundamental part is followed by giving the sources of radon and thoron indoors, and thus, their products, and displaying the dependence of their levels on the ground characteristics, building material and practice, and living–working habits of residents. Substantial hourly, daily, and seasonal changes in their activity concentrations are reviewed, as influenced by meteorological parameters (air temperature, pressure, humidity, and wind speed) and human activity (either by ventilation, air conditioning and air filtration, or by generating aerosol particles). The role of the aerosol particle concentration and their size distribution in the dynamics of radon products in indoor air has been elucidated, focusing on the fraction of unattached products. Intensifying combined monitoring of radon short-lived products and background aerosol would improve radon dosimetry approaches in field and laboratory experiments. A profound knowledge of the influence of meteorological parameters and human activities on the dynamics of the behaviour of radon and thoron accompanied by their products in the air is a prerequisite to managing sustainable indoor air quality and human health.
