Radon exhalation rates of some granites used in Serbia [PDF]

Nuclear Technology and Radiation Protection, 2015
In order to address concern about radon exhalation in building material, radon exhalation rate was determined for different granites available on Serbian market. Radon exhalation rate, along with mass exhalation rate and effective radium content

Radon Exhalation Rate: A Metrological Approach for Radiation Protection. [PDF]

Sensors (Basel)
Radon, a radioactive inert gas that comes from the decay of naturally occurring radioactive species, poses a substantial health risk due to its involvement in lung cancer carcinogenesis. This work proposes a metrological approach for determining radon exhalation rates from diverse building materials. This methodology employs an electrostatic collection

Investigation of the influence of chamber construction parameters on radon exhalation rate [PDF]

Nukleonika, 2016
Radon exhalation from ground is a process dependent on the emanation and migration of radon through ambient air. Most studies on radon exhalation from soil were performed regarding the influence of meteorological and soil parameters.

Estimation of global radon exhalation rate distribution [PDF]

AIP Conference Proceedings, 2008
A 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 ...

Experimental study on gas permeability and radon control performance of red clay covering layer on uranium mill tailings pond [PDF]

Scientific Reports
The decommissioning of uranium mill tailings pond generally employs covering layer to diminish radon exhalation, with soil permeability, thickness, and moisture content being essential considerations in assessing the efficacy of radon reduction.

Edaphic and meteorological parameters as determinants of radon exhalation and its environmental implication in Peruvian agroecosystems [PDF]

Scientific Reports
Radon exhalation is a natural process by which atoms of the radioactive gas radon diffuse in the soil and then exhale to an indoor and/or outdoor environment.

Soil radon exhalation rate measurement in Duhok city by two techniques [PDF]

Nuclear Technology and Radiation Protection, 2022
Radon exhalation rate is the rate of radioactive radon gas that escapes from the soil into the atmosphere. In this study exhalation rate of radon was measured for 33 samples of soil, in four districts of Duhok province, using two different ...
