Questions & Answers

Q: What is radon and where does it come from?

Radon is a radioactive gas that is generated from the decay of uranium and thorium in the Earth's crust. It seeps up from the ground and can accumulate in homes.

Q: How is radon detected in homes?

Radon can be detected using detection kits or digital radiation meters. These devices measure the concentration of radon in the air and determine if it is at dangerous levels.

Q: What are the health risks associated with radon exposure?

Exposure to radon increases the risk of lung cancer. Non-smokers have a 2% increased risk when exposed to radon at levels around 200 becquerels per cubic meter. Smokers have a significantly higher risk.

Q: What can be done to mitigate the risks of radon exposure?

To reduce radon concentrations, cracks in the foundation can be sealed, gaps around pipes can be closed, radon traps can be installed, and positive pressure ventilation can be introduced. Government guidelines recommend radon levels below 200 becquerels per cubic meter in living areas.

Summary & Key Takeaways

  • Radon is a radioactive gas that is colorless, odorless, tasteless, and chemically inert.

  • It is continuously generated from the decay of radioactive elements like uranium and thorium in the Earth's crust.

  • Radon accumulation in homes can reach potentially dangerous concentrations and increase the risk of lung cancer.
