Introduction
Indoor radon exposure is a major environmental health issue, yet it often
goes unnoticed due to the gas’s undetectable nature — it is invisible, odorless,
and tasteless. Radon originates from the natural decay of uranium in soil and
rocks and can enter buildings through foundations and construction materials.
Prolonged inhalation of radon is a well-established risk factor for lung cancer
and has been identified by the World Health Organization (WHO) as the second
most common cause of the disease globally, after tobacco use.
In Uzbekistan, and specifically in the capital city of Tashkent, there is a lack
of comprehensive data on how building-related factors affect radon
accumulation indoors. The city features a mix of traditional and modern housing
constructed from diverse materials, such as brick, concrete, and clay — each
with different properties in terms of radon permeability and emission potential.
This study seeks to evaluate how the type and condition of building
structures influence indoor radon levels in residential areas of Tashkent. The
goal is to support safer housing policies and inform construction practices that
reduce environmental health risks.
Main Body
This investigation focuses on radon levels in homes built using various
construction materials, with attention given to structural quality and ventilation
efficiency. The research sample includes approximately 50 residential buildings
across multiple districts of Tashkent, selected to represent different
architectural styles, construction periods, and geological settings.
Measurements will be carried out using calibrated digital radon monitors
placed in commonly used indoor spaces — such as bedrooms, living rooms, and
basements — to capture reliable exposure data. These readings will be
accompanied by an analysis of ventilation systems, room usage patterns, and
building maintenance status.
A critical component of the study will involve evaluating the materials used
in wall and foundation construction. For instance, materials like hollow clay
bricks may allow greater radon penetration due to their porosity, while concrete
— though denser — may still allow radon entry if cracked or improperly sealed.

The study will also assess the potential radon contribution of locally sourced
materials by examining their uranium content.
To enhance accuracy, soil composition data and geological mapping of
radon-prone zones will be integrated into the analysis. Statistical tools, including
multivariate regression and correlation analysis, will help identify the most
influential variables associated with indoor radon variation.
The study will also draw comparisons with international research findings
to contextualize the situation in Tashkent and help determine if existing global
safety thresholds are applicable or require local adaptation.
Conclusion
This research will deliver evidence-based insights into how construction choices
influence radon exposure in urban Uzbek homes. The findings are expected to
guide health-conscious building strategies, including the selection of low-radon-
emitting materials and the design of effective ventilation systems.
By highlighting structural risk factors and regional vulnerabilities, the study
will contribute to developing public health policies, building regulations, and
awareness campaigns aimed at reducing radon-related disease burdens in
Tashkent. Proactive risk management at the construction phase can lead to safer
living environments and a measurable decrease in radon-induced health
outcomes.
