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 ...

RADON INHALATION EXPERIMENTS TO TEST RADON EXHALATION KINETICS
Radiation Protection Dosimetry, 2020 Abstract Three experiments were conducted with a volunteer to test the kinetics of the 222Rn exhalation after a shorttime exposure to an elevated 222Rn air concentration. Radon concentration in an exhaled air was measured, complemented by whole body counting of 222Rn decay products in a body.

Estimation of global radon exhalation rate distribution [PDF]
, 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 ...
