RADON TESTING AND MITIGATION SERVICES

What is Radon? Radon is a naturally occurring radioactive gas that is tasteless, odorless, and colorless. It comes from the radioactive decay (breakdown) of radium, which comes from the radioactive decay of uranium, both of which are found in at least trace amounts in almost any kind of soil or rock. Granites, shales, phosphates, and certain other types of rock have higher than average concentrations of uranium, and as such, may produce higher concentrations of radon. However, elevated radon levels can occur even in areas with low concentrations of uranium in the soil or rocks.


Compliance, Inc. can provide certified individuals (NEHA) for testing and mitigation services for residential and commercial applications.

National Radon Safety Board Certification #9G0008

Radon Potential - Radon testing performed by the State of Michigan found that approximately 12% of all homes would have radon screening levels greater than 4 picocuries per liter (pCi/l) of air (the recommended action guideline set by EPA). In some counties, as many as 40-45 percent (or more) of the homes would have screening levels above the 4 pCi/l guideline.


TYPICAL RADON MITIGATION COSTS
If it has been determined from radon testing that radon mitigation is necessary, Compliance, Inc. can install a Radon Mitigation System. The costs range between $400.00 for a passive system to $2,500.00 for an extensive, active system.

At times radon test results may report radon levels just above 4.0 pCi/l. In these cases Compliance, Inc. may recommend methods the homeowner can perform to achieve a level below 4.0 pCi/l.

EPA Recommends

  • Test your home for radon — it's easy and inexpensive.
  • Fix your home if your radon level is 4 picocuries per liter (pCi/L), or higher.
  • Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced.

Graph comparing Radon Deaths per year to other causes of death


Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA's 2003 Assessment of Risks from Radon in Homes (EPA 402-R-03-003). The numbers of deaths from other causes are taken from the Centers for Disease Control and Prevention's 2005-2006 National Center for Injury Prevention and Control Report and 2006 National Safety Council Reports.

Examples of how radon gas enters a building:

Radon Example 1Radon Example 2Radon Example 3

Windblown Effect:  Wind hitting one side of a house can create a positive pressure situation, increasing the rate of soil gas migration into a basement.  Wind can also create a negative pressure effect in the house, increasing the stack effect.

Rainfall Effect: : Rainfall seeping into the soil creates a saturated layer that rising soil gas cannot easily penetrate. The gas follows the path of least resistance, which is often into a basement.

The Stack Effect: Warmer, lighter air rising through a house creates a lower pressure in the basement, which increases air flow in to the basement from the subsurface.
