Measurement of Radon Concentration Using SSNTD in Bartella Region

Al-Mustansiriyah Journal of Science, 2019
The alpha-radioactive inert gas Radon exhalation is associated with presence of Radium and its ultimate precursor uranium in the earth crust. Uranium decay deposits radon in soil, which is harmful on human and environment.

Effect of the altitude on the concentration and exhalation rate of radon

International Journal of Low Radiation, 2014
High altitude is characterised by hypoxic and hypobaric conditions. Exposure to high altitude is known to affect human physiology, specially blood oxygen tension and saturation. Also, oxygen, carbon dioxide and vacuum are known to affect some polymers used in radon detection.

Determination of Radon Exhalation Rates from Tiles (Marble, Granite and Ceramic) Using LR115 Type II Passive Technique

مجلة علوم ذي قار, 2019
Exhalation of 222Rn, ?-radioactive inert gas, is associated with the presence of 226Ra and it's ultimate precursor uranium in the earth crust. It is a useful quantity to compare the relative importance of different materials of tiles (marble, granite and

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

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.

Right main pulmonary artery distensibility on dynamic ventilation CT and its association with respiratory function

European Radiology Experimental
Background Heartbeat-based cross-sectional area (CSA) changes in the right main pulmonary artery (MPA), which reflects its distensibility associated with pulmonary hypertension, can be measured using dynamic ventilation computed tomography (DVCT) in ...
