The American Association of Radon Scientists and Technologists (AARST) announced that a new standard, ANSI/AARST CCAH-2013, “Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses” was approved on January 11, 2013 by the American National Standards Institute (ANSI).
The new standard, referred to as RRNC 2.0, was promulgated by the AARST consensus standards writing consortium and provides code specific language for dealing with radon in new construction. The new RRNC 2.0 standard provides a tool to make sure that new homes do not create radon risk for occupants or long term liabilities for developers, bankers and builders.
David Kapturowski, Vice President of AARST, and Chair of the AARST standards committee that created the new document, said that this will be an important contribution to radon risk reduction in the United States.
“Unfortunately, there are more homes in the United States today with elevated indoor radon levels than there were 25 years ago,” said Kapturowski, “because the rate of radon mitigation has simply not kept pace with the rate of new home construction." More

Leadership problems concerning radon
The question is no longer if radon gas is a threat; it’s whether or not our local, county, state and Federal representatives will provide leadership in this area.
In Virginia, only 2 counties have adopted the IRC codes pertaining to radon resistance construction. Virginia has 48 counties in EPA Zone 1.
Think about it, we all think we are the safest while in our homes. For instance, a house having 4 pCi of radon per liter of air has about 8 or 9 atoms of radon decaying every minute in every liter of air inside the house. A 1,000 square foot house with 4 pCi/L of radon has nearly 2 million radon atoms decaying in it every minute. That 4 pCi/l action level doesn't seem to low does now does it.
