ANSI-AARST Standard: Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses
ANSI/AARST has released "RRNC 2.0 Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses" to control for radon in the construction of new residential homes. The standard, designated CCAH-2013, is written in code language. Copies are available for $45 each for non-members, $30 each for AARST members from AARST at www.aarst.org/bookstore.shtml .
In cooperation with EPA's Indoor Environments Division, the American Society of Home Inspectors (ASHI) created the Radon Mitigation System Inspection Checklist. With just seven inspection elements, the Checklist takes under 15 minutes to complete. Builders can also use the checklist as a guide during the home building process. The checklist can be given to the home buyer to confirm the RRNC features installed. Revised January 9, 2009.

Produced for EPA by the National Association of Home Builders Research Center Inc., this report for calendar 2010 is available as a PDF from the National Service Center for Environmental Publications (NSCEP) - http://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P100DS62.txt. Reference EPA document number 402-K-12-001. The report includes information on radon-resistant home building practices for single-family homes, multifamily buildings, trends, costs and demographics.
EPA is making the report available in the belief that individuals, builders, state/local governments, researchers, and radon professionals will find it useful. Voluntary adoption of radon-resistant new construction techniques by builders and building code authorities is an EPA radon program priority.
