HEALTH RISKS OF RADON
Radon is invisible, yet it is one of the major harmful substances that
may affect indoor air quality and human health.
Radon, a Group 1 Carcinogen Designated
by the WHO
Cancer-causing Substance Exposure
Proportion of Lung Cancer Causes in Korea
Radon is a colorless, odorless, and tasteless radioactive gas that is mainly generated from natural sources such as soil and rock and may enter indoor spaces.
The World Health Organization classifies radon as a Group 1 carcinogen and reports that long-term exposure to high concentrations of radon may affect human health.
Because radon can accumulate in the lungs, regular monitoring and proper management are especially important in indoor environments.
As an invisible risk, radon requires accurate measurement and a response based on reliable standards.
In Korea, the recommended indoor radon guideline is 148 Bq/m³. Continuous management is required to ensure that indoor radon levels do not exceed this standard.
Health Risks of Radon
Although radon cannot be seen, continuous exposure may affect human health.
Occupational Exposure
Special caution is required in poorly ventilated spaces such as underground workplaces, mines, and tunnels.
Carcinogenicity
IARC Group 1 — a major risk factor for lung cancer.
Research Findings
Studies of underground miners have confirmed an increased risk associated with radon exposure.
