Indoor radon concentrations in Adana, Turkey

Area of Science:

• Environmental Science
• Radiological Protection
• Public Health

Background:

• Radon (Rn) is a naturally occurring radioactive gas linked to lung cancer.
• Indoor radon concentration varies geographically and seasonally.
• Understanding indoor radon levels is crucial for public health risk assessment.

Purpose of the Study:

• To measure indoor radon concentrations in Adana, Turkey.
• To assess seasonal variations in indoor radon levels.
• To estimate the annual effective dose equivalent from indoor radon exposure.

Main Methods:

• Indoor radon concentrations were measured in living rooms of 52 houses (winter) and 57 houses (summer).
• CR-39 passive nuclear track detectors were used for seasonal measurements over 60-day periods.
• Forty-four houses were monitored in both winter and summer to analyze seasonal differences.

Main Results:

• Winter radon concentrations ranged from 15 to 97 Bq m⁻³, averaging 48.9 Bq m⁻³.
• Summer radon concentrations ranged from 5 to 70 Bq m⁻³, averaging 25.8 Bq m⁻³.
• The average annual indoor radon concentration (37 Bq m⁻³) was below the worldwide average (46 Bq m⁻³), with an annual effective dose of 0.9 mSv y⁻¹.

Conclusions:

• Indoor radon concentrations in Adana are significantly higher during winter than summer.
• The average indoor radon levels in Adana are below the global average, suggesting a relatively lower lung cancer risk from radon.
• Seasonal monitoring is essential for accurate assessment of indoor radon exposure and associated health risks.
