Is radon equally dangerous for everyone or more dangerous for children?

Radon is the leading cause of lung cancer among nonsmokers. Children are at greater risk for lung cancer from radon exposure because their lungs are smaller and still developing. Radon decays into radioactive particles that can get trapped in your lungs, causing tissue damage that ultimately leads to lung cancer. Radon is also increases the risk of lung cancer in smokers because their lungs are already compromised. 

Is radon a concern in newer homes?

Yes. Radon can enter a home through cracks and holes in the foundation, floors and walls including construction joints, gaps in suspended floors and around service pipes, wall cavities and the water supply. According to the EPA, nearly one out of every 15 homes in the U.S. is estimated to have elevated radon levels.

How can I test my home for radon?

Radon is measured in picocuries per liter of air (pCi/L). Purchase a short term test that includes lab results to measure the levels in your home. If the lab results reveal a level of 4 pCi/L or higher, follow up with a long-term test. If the average results are 4 pCi/L or higher, you will need to hire a qualified contractor to install a radon mitigation system. Kits are available online or at your local hardware store. Local health departments often offer free test kits. Because radon levels can fluctuate, it’s a good idea to test your home once a year, alternating the season in which you test.

What is radon and where does it come from?

Radon is a radioactive gas found in soil. It produced by the natural decay of uranium. Radon travels up through the ground and into the air. It can easily pass through the foundation of your home through cracks and holes. The highest risk for radon exposure is inside your home because the walls trap the gas and it builds to higher concentrations. It can be found anywhere, but there are certain parts of the U.S. that have higher levels.

What levels of carbon monoxide are dangerous?

The presence of carbon monoxide means you are breathing in less oxygen. Health effects can be chronic or acute. Effects also depend on the individual’s age and health. Concentrations are measured in parts per million (ppm).  A home with fuel burning appliances will often have regular levels below 8 ppm. When these levels are higher than 8 ppm, one of the appliances may be malfunctioning. Exposure up to 70 ppm will not cause acute effects, but overtime may lead to chronic headaches, fatigue, chest pain and nausea, especially in the elderly or those with compromised immune systems. Many will not experience symptoms at levels below 70 ppm. When CO levels are above 70 ppm, these symptoms will become noticeable or more severe. Levels above 150 ppm will cause acute CO poisoning, leading to disorientation, unconsciousness and death.  Most store-bought alarms will sound after one hour of reading 70 ppm. When a CO alarm sounds, leave the home immediately and dial 911 from outside.
