Radon and thoron exhalation rate, emanation factor and radioactivity risks of building materials of the Iberian Peninsula. [PDF]
PeerJ, 2020 Radon (222Rn) and thoron (220Rn) are radioactive gases emanating from geological materials. Inhalation of these gases is closely related to an increase in the probability of lung cancer if the levels are high.

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 ...

Evaluation of Exhaled Nitric Oxide in Schoolchildren at Different Exhalation Flow Rates [PDF]
Pediatric Research, 2002 Nitric oxide (NO) in exhaled air is believed to reflect allergic inflammation in the airways. Measured levels of exhaled NO vary with the exhaled flow rate, which therefore must be standardized. The aim of this study was to estimate the optimal exhalation flow rate when measuring NO in exhaled air.
