Radon exhalation from granites used in Saudi Arabia
Journal of Environmental Radioactivity, 2001Measurements of radon exhalation for a total of 50 selected samples of construction materials used in Saudi Arabia were taken using a radon gas analyzer. These materials included sand, aggregate, cement, gypsum, hydrated lime, ceramics and granite. It was found that the granite samples were the main source of radon emanations.

Estimation of global radon exhalation rate distribution
AIP Conference Proceedings, 2008A radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates were calculated to be 17.5 and 18.0 mBq⋅m−2⋅s−1 by the model with different input soil moisture data.

Uranium distribution and radon exhalation from Brazilian dimension stones
Applied Radiation and Isotopes, 2012This paper provides evaluations of the radiometric behavior and exhalation patterns of radon gas in decorative and dimension stones explored in the Brazilian states of Minas Gerais and Espírito Santo, given the importance of determining radon gas concentrations in human-inhabited environments.

Radon Exhalation Rates and Gamma Doses from Ceramic Tiles
Health Physics, 1998This study was carried out to assess the possible radiological hazard resulting from the use of zircon in glaze applied to tiles used in buildings. The 226Ra content of various stains and glazing compounds was measured using gamma spectroscopy and the 222Rn exhalation rates for these materials were measured using adsorption on activated charcoal.

Issues of Radon (Rn-222) Exhalation Measurements
2014The Rn-222 isotope, a naturally occurring radioactive gas, is created in a radioactive decay of Ra-226. Both radionuclides belong to the radium decay chain in which U-238 is the prime parent. Radon is usually in plenty found in the earth crust, rocks, soil, water and air, therefore it is regarded as an indicator of ionizing radiation dose received by a
