Radon Mitigation (Reduction)
Contractor Proficiency List -- Wisconsin 

There are no state regulations specifically for radon mitigation businesses in Wisconsin. The proficiency list below is combined from two national certifying organizations, whose web sites carry the most up-to-date information:

To be listed by them, an individual must pass a national exam, meet continuing education requirements and follow radon mitigation standards.  (For information on radon mitigation proficiency training to be held in Wisconsin, please contact the Radiation Protection Section, 608 267-4795 or the EPA regional radon training center, 800 843-8636.)

Being listed on this page does not constitute endorsement by the State of Wisconsin, or the Department of Health Services.  The lists are provided as an additional resource for interested individuals.

Radon Mitigation Contractor Proficiency List -- Wisconsin
 (June 2008):   

FOR A DURABLE, EFFICIENT SYSTEM TO CONTROL RADON, INSIST THAT IT MEET MITIGATION STANDARDS.  The fan must be outside the basement and the exhaust stack must go up to the roof, - at least 10 feet above ground and 2 feet above any windows less than ten feet away.  The exhaust is blowing out 50 cubic feet of air per minute with a radon concentration of several hundred pCi/L, possibly a thousand pCi/L.  If released at the sill of a house, some of this radon can enter the house through openings at the sill plate (where the basement sucks it in), and, at times, windows.  Studies have shown  the average indoor radon can be increased by one pCi/L or more by these effects.  In addition, experience by EPA contractors shows that the joints and couplings to radon fans tend to leak radon on the high pressure side, significantly reducing the effectiveness of mitigation systems with fans in basements.  For a list of mitigation system standards see the US EPA booklet Consumer's guide to Radon Reduction, p. 12, at the EPA radon Website, or call a Wisconsin Regional Radon Information Center toll-free, 888-LOW-RADON.
