Comparison of measured exhaled nitric oxide at varying flow rates [PDF]

open access: yesThorax, 2005
Altered levels of exhaled nitric oxide (FeNO) have been well documented in a number of conditions, although it is in asthma that this phenomenon has been most extensively investigated.1 Raised FeNO levels in patients with asthma have been correlated not only with other markers of airway inflammation (including induced sputum eosinophil count), but also

Radon-thoron measurements in air and soil from some districts of northern part of India [PDF]

open access: yesNuclear Technology and Radiation Protection, 2015
Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques.

Investigation of the influence of chamber construction parameters on radon exhalation rate

open access: yesNukleonika, 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.

INFLUENCE OF SAMPLING FLOW RATE ON THORON EXHALATION RATE MEASUREMENTS BY THE CIRCULATION METHOD

open access: yesRadiation Protection Dosimetry, 2022
AbstractResearchers have used various methods to obtain the exhalation rates of radon and thoron from soil and building materials. One of the typical methods for radon exhalation rate is the circulation method using an accumulation container, an external or internal sampling pump and a continuous radon monitor.

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity

open access: yes, 2017
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals.
