Building healthy buildings is one of the building sector’s current objectives. Radon gas can have a significant effect on an area’s residents and users, so controlling it is essential. What effect does radon gas have on our health?
Radon affects our health. According to WHO estimates, the proportion of lung cancer cases attributable to radon varies between 3% and 14% of the total.
During its final phase of disintegration, radon escapes into the air, where it decays and produces radioactive particles. As we breathe and inhale the particles, they are deposited on the cells lining the airways, where they can damage DNA and cause health problems.
Does radon cause cancer?
An increased rate of lung cancer was first detected in uranium miners exposed to high concentrations of radon gas. In addition, studies have confirmed that even at low concentrations, such as those found in buildings, radon also poses health risks and contributes significantly to the occurrence of lung cancer across the world.
The risk of lung cancer increases by 16% per 100 Bq/m3 increase in the average radon concentration over time. Therefore, the risk of lung cancer increases in proportion with increased exposure to radon. So far, no other cancer risks attributable to radon have been established.
Water contaminated with radon gas
Epidemiological studies have not found any link between consuming drinking water containing radon and an increased risk of stomach cancer. However, radon dissolved in drinking water can affect the health of residents and users of interior spaces too.
The WHO Guidelines for Drinking Water Quality recommend that levels of radon concentration in drinking water are set based on the national reference level for radon in air. In circumstances where high radon concentrations might be expected in drinking water, it is wise to measure radon concentrations.
