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.

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

Radon and thoron exhalation rate in the soil of Western Haryana, India
Environmental Monitoring and Assessment, 2022 Abstract This study, reports the exhalation rates of radon and thoron from surface soil collected from 60 rural sites of district Hisar, Haryana, India. The exhalation rates of Rn222 (Radon)& Rn220(Thoron) were measured by portable SMART RnDuo (AQTEK SYSTEMS) using a mass accumulation chamber which is equipped with a scintillation material ...
