Lasting passive examinations will measure your house's radon levels for 90 days to a year. You can also purchase a lasting examination online for $25 from Kansas State, or with a merchant like

As a matter of fact, the radon gas focus comes close to history degrees at 3-4 feet from the discharge factor. The concentration of radon gas at the discharge factor can be tens of hundreds of picocuries per minute. The words radon test "failed" or radon test "passed" are sprayed around. The USA EPA has developed the radon degree of 4.0 picocuries per liter to be the activity degree for radon gas in homes.

If a person has been exposed to radon, 75 percent of the radon progeny in lungs will become "harmless" lead particles after 44 years. When an alpha particle damages a cell to make it cancerous, the onset of lung cancer takes a minimum of 5 years but most often 15 to 25 years, and even longer.

Can radon be completely eliminated?

Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.
