Boise Radon Testing: What Every Homeowner Should Know
Boise radon testing is one of the top environmental tests homeowners have done. When it comes to buying a home or ensuring the safety of your current residence, many homeowners overlook one critical factor: radon. Radon testing in Boise is essential because radon is a colorless, odorless, and tasteless radioactive gas that can pose serious health risks if left undetected. At Treasure Valley Home Inspectors, we emphasize the importance of radon testing as part of our comprehensive Boise home inspection services or as a standalone service for those looking to assess their current living conditions. Idaho does not currently regulate radon testing in Boise. However, around 40% of all homes tested had higher than recommended radon levels. Radon testing is fairly inexpensive.

What is Radon?
Radon is a naturally occurring gas that results from the breakdown of uranium in soil, rock, and water. It seeps into homes through cracks in the foundation, walls, and other entry points. Once inside, radon can accumulate to dangerous levels, posing a significant health risk to you and your family. Radon is the leading cause of lung cancer! This is why radon testing is so important. According to the EPA, testing is the only way to know your level of exposure.

Because of this, the geological makeup of our region contributes to this, making radon testing in Boise homes not just a precaution but a necessity for homeowners. According to the Environmental Protection Agency (EPA), radon exposure is the second leading cause of lung cancer in the United States, following smoking.
Local Statistics on Radon Testing in Boise
Studies have shown that over 30% of homes in Boise have radon levels above the EPA’s action level of 4.0 picocuries per liter (pCi/L). However, some areas in the Treasure Valley have even reported levels exceeding 10 pCi/L, highlighting the importance of regular radon testing.
