Radon Procedure

Radon is not a medical procedure, but rather a naturally occurring radioactive gas that can be found in soil, water, and air.

What is Radon?

Radon is a colorless, odorless, and tasteless gas that is produced by the breakdown of uranium in soil, rocks, and water. It is a known carcinogen and can increase the risk of lung cancer when inhaled in large quantities.

How is Radon Measured?

Radon levels are typically measured in picocuries per liter (pCi/L) or becquerels per cubic meter (Bq/m³). The United States Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if they exceed 4 pCi/L.

Health Risks Associated with Radon

Long-term exposure to high levels of radon can increase the risk of developing lung cancer. According to the EPA, radon is responsible for approximately 21,000 lung cancer deaths per year in the United States.

Reducing Radon Levels

There are several methods to reduce radon levels in homes and buildings, including:

  • Sealing entry points, such as cracks and crevices in foundations and walls
  • Installing a radon-resistant barrier in crawl spaces
  • Using a ventilation system to remove radon from the soil beneath a building
  • Installing an active soil depressurization system, which involves drilling a hole into the soil and using a fan to draw out radon

Testing for Radon

Radon testing can be done using various methods, including:

  • Short-term tests, which typically take 2-7 days to complete
  • Long-term tests, which can take 3-12 months to complete
  • Continuous radon monitors, which provide real-time readings of radon levels

Regulations and Guidelines

The EPA has established guidelines for radon levels in homes and buildings. The agency recommends taking action to reduce radon levels if they exceed 4 pCi/L. Some states and local governments have also established their own regulations and guidelines for radon testing and mitigation.
