Radon
Radon is a colorless, odorless radioactive gas that occurs naturally from the decay of uranium in soil, rock, and water. It can seep into buildings through cracks in foundations and accumulate to dangerous levels, particularly in basements and lower floors.
Example
“The home inspection revealed elevated radon levels in the basement, requiring a mitigation system before the sale could proceed.”
Memory Tip
Remember 'radon' sounds like 'ray-don' - it's a radioactive gas that sends out invisible rays that can harm your lungs.
Why It Matters
Radon is the second leading cause of lung cancer after smoking, making radon testing an important part of home inspections to protect occupant health.
Common Misconception
Many homebuyers assume that newer homes don't have radon problems, but any home can have elevated radon levels regardless of age or construction type.
In Practice
During a home inspection, elevated radon levels are discovered in a basement, prompting the buyer to negotiate for the seller to install a radon mitigation system before closing.
Etymology
Named after the element radium by German chemist Friedrich Ernst Dorn in 1900, with the suffix '-on' following the pattern of noble gas names like argon.
