Assessment of Indoor Radon Exposure Risks in Relation to Dwelling Types in Gold‐Mining Communities of Akyempim, Wassa East District, Ghana

Indoor Air, Volume 2026, Issue 1, 2026.
This study investigated the effects of dwelling type, wall and floor coverings, radium‐226 concentration, soil moisture, and radon exhalation on indoor radon‐222 levels in the gold‐mining community of Akyempim, Ghana. Indoor radon was monitored using CR‐39 solid‐state nuclear track detectors deployed in 144 rooms across 21 sites for 90 days ...

Inequality in Burden of Tracheal, Bronchial, and Lung Cancer Attributable to Residential Radon Exposure: Global Analysis and Country‐Level Patterns in High Granite/Marble Consuming Countries

Indoor Air, Volume 2026, Issue 1, 2026.
Backgrounds Radon is the second leading cause of lung cancer, accounting for 3%–14% of cases worldwide. Aim To assess global and national trends in tracheal, bronchial, and lung (TBL) cancer attributable to residential radon from 1990 to 2021 and to project trends up to 2046. Methods The Global Burden of Disease (GBD) 2021 data were utilized to analyze

Low‐Carbon Concrete Systems: A Comparative Review of Binder Technologies and Alternative Materials

Journal of Engineering, Volume 2026, Issue 1, 2026.
About 8% of the world′s carbon dioxide emissions come from the production of concrete, mostly from the clinker used to make regular Portland cement. By comparing supplementary cementitious materials (SCMs), alkali‐activated materials (AAMs), alternative aggregates, and waste‐derived elements using a shared carbon‐performance paradigm, this review ...

Radon exhalation rate in south-east Sicily building materials

, 2015
One of the main contributions to indoor radon levels is given by the exhalation from building materials. For this reason we performed measurements of radon exhalation rate in materials commonly used in buildings of the eastern Sicily.

Oxidative Stress in Neonatal Disease: Established Organ Injury and Emerging Evidence for Skeletal Involvement

Oxidative Medicine and Cellular Longevity, Volume 2026, Issue 1, 2026.
Reactive oxygen and nitrogen species participate in physiological signaling and adaptation during fetal and neonatal development, whereas excessive, prolonged, or spatially dysregulated production may contribute to oxidative and nitrosative tissue injury.

Indoor radon and thoron from building materials: Analysis of humidity, air exchange rate, and dose assessment

Nuclear Engineering and Technology, 2020
Building materials contribute significantly to the indoor radon and thoron levels. Therefore, parameters that influence the exhalation rates of radon and thoron from building material need to be analyzed closely.

Aspects of an instrument for in situ measurements of radon exhalation rates

Environment International, 1988
The properties of an instrument for in situ measurements of radon-exhalation rates were investigated. Rather than enclosing the sample in a measuring volume this instrument consists of a hood which is to be placed with its open end onto the sample. By applying an electric field positively charged radon-decay products are collected on an aluminised ...

Investigation of key parameters influencing 222Rn exhalation rate from selected industrial and environmental samples using AlphaGUARD monitor

Scientific Reports
Radon-222 (222Rn) exhalation from natural and building materials is a significant source of indoor radiation exposure, yet the effects of key physical parameters controlling radon release remain insufficiently understood.

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.
