[Summary of article]
1. Radon level survey
The level of radon, a radioactive substance, in newly built apartments in the metropolitan area was measured at an average of 1,125.79 Becquerel (Bq/㎥) and a maximum of 1,733.08 Becquerel (Bq/㎥), which is more than seven times the Ministry of Environment's safety standard.
2. Radon in building materials
Cement products have been identified as one of the reasons for high radon levels in new apartments. Experiments have shown that radon emissions increase rapidly when cement is mixed with water and turns into concrete.
3. Radon levels by construction company
Radon levels exceeding standards have been detected in newly built apartments from several construction companies, despite the presence of ventilation systems.
4. Lung cancer incidence
According to Statistics Korea, the lung cancer mortality rate is the highest at 35.1%, and the incidence of lung cancer is on the rise despite the decline in the number of smokers.
5. Environmental impact
Smoking and fine dust are known to be the main causes of lung cancer, but radon generated in residential spaces such as apartments is also identified as an important cause.
6. International Research
Overseas studies have already shown that radon emissions increase when cement reacts with water to form concrete.
7. Policy Proposals
The article emphasizes that government investigation and countermeasures are needed for these issues.
