Radon 101 – Basic Information

What is Radon?
Radon is a naturally occurring radioactive gas that is colorless, odorless, and tasteless. It is produced from the natural decay of uranium found in soil, rock, and water.

Why is Radon Important?
Radon is important because it is a leading cause of lung cancer after smoking. When radon gas accumulates indoors, especially in basements and lower levels of buildings, it can pose serious health risks.

How Does Radon Enter Homes?
Radon moves up through the soil and can enter buildings through cracks in floors, walls, construction joints, gaps around pipes, and other openings.

Health Risks

  • Long-term exposure to high levels of radon increases the risk of lung cancer.
  • Radon is responsible for thousands of lung cancer deaths annually worldwide.
  • Smokers exposed to radon have a much higher risk of lung cancer.

Testing for Radon

  • Radon testing is the only way to know how much radon is in your home.
  • Testing kits are affordable and easy to use.
  • Testing should be done in the lowest lived-in level of the home.
  • Short-term tests last from 2 to 7 days; long-term tests last more than 90 days.

Reducing Radon Levels

  • If high radon levels are found (above 4 pCi/L or 100 Bq/m³), mitigation is recommended.
  • Common methods include soil suction systems, sealing cracks, and improving ventilation.
  • Professional radon mitigation services can effectively reduce radon levels.

Summary
Radon is a dangerous, invisible gas that can accumulate indoors and increase lung cancer risk. Testing and mitigation are key to protecting your health and home.
