Radon is the second-leading cause of lung cancer, with 21000 deaths per year in the US, as per reports from the United States Environment Protection Agency (EPA).
About Radon:
- Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals, break down in rocks, soil, and groundwater.
- It is an inert, colourless, and odourless gas.
- Radon gas usually exists at very low levels outdoors, but the gas can accumulate in areas without adequate ventilation, such as underground mines.
- Radon can get into homes and buildings through small cracks or holes and build up in the air.
- Radon levels may be higher in homes that are well insulated, tightly sealed, and/or built on soil rich in the elements uranium, thorium, and radium.
- As we breathe, these particles are deposited on the cells lining the airways, where they can damage DNA and potentially cause lung cancer.
- It is the second-most important cause of lung cancer after smoking and the leading cause of lung cancer among non-smokers.
- According to the WHO, radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence.
Hence only statement 1 is correct.
