Radon is a naturally occurring, colorless, odorless, and tasteless inert gas that results from the radioactive decay of radium. It is a radioactive gas commonly found in our living environments. Since its discovery in indoor spaces during the late 1960s, studies have shown that radon exposure contributes significantly to the total environmental radiation people receive. More than 55% of this radiation is considered extremely harmful to human health, with most effects having long incubation periods of over 15 years. The International Agency for Research on Cancer (IARC) has classified radon as an important indoor carcinogen, and the U.S. Environmental Protection Agency also ranks it among the most dangerous carcinogens. Therefore, it is essential to pay close attention to the risks associated with indoor radon. Radon enters homes through various sources. Approximately 60.4% comes from the soil beneath the foundation, while 19.5% originates from building materials and 17.8% from outdoor air. Firstly, radon can be released from the soil due to the presence of uranium, radium, and thorium. These elements can generate radon gas, which seeps through cracks and enters buildings, especially in low-rise structures where the concentration tends to be higher. Secondly, building materials such as concrete, bricks, and decorative items may contain radium, which can release radon over time. The amount of radon emitted depends on factors like the material’s porosity, particle size, and moisture content. Thirdly, radon from outdoor air can enter homes through open windows, doors, or ventilation systems. Indoor radon levels are often higher in winter and lower in summer, emphasizing the importance of proper ventilation. Fourthly, radon can also come from water and natural gas, particularly when these sources contain high levels of strontium. The dangers of radon were first recognized over 100 years ago in Germany, where miners in the Sniberg area developed high rates of lung cancer, later identified as "Sniberg disease." Radon was finally linked to lung cancer in the 1950s, leading to increased awareness of its health risks. Radon exposure affects the body in two main ways: deterministic and stochastic effects. Deterministic effects include changes in blood cells, while stochastic effects involve the risk of cancer. As a radioactive gas, radon and its decay products emit alpha particles that can damage lung tissue, increasing the risk of lung cancer. Studies show that radon is the second leading cause of lung cancer after smoking, responsible for about 15% of all cases. Children are especially vulnerable, as their developing bodies are more sensitive to radiation. The lungs receive the highest dose of radiation, and the effective dose is significantly higher in young children compared to adults. Long-term exposure to radon increases the risk of lung cancer, leukemia, infertility, and fetal malformations. To reduce radon levels indoors, several measures can be taken. Frequent ventilation helps maintain equal pressure between indoor and outdoor air. Installing insulation layers in new homes can minimize radon entry. Using anti-radon coatings on walls and floors can also help reduce emissions. Products like RadonSeal are designed to seal surfaces and prevent radon infiltration. Environmentally friendly paints with improved sealing properties are also available to help control indoor radon levels. By taking these steps, individuals can significantly reduce their exposure to this harmful gas and protect their health.
