The NKBA offers professional advice regarding granite countertops and radon emissions
Associate Kitchen & Bath Designers (AKBDs), Certified Kitchen Designers (CKDs), Certified Bathroom Designers (CBDs), and Certified Master Kitchen & Bath Designers (CMKBDs) are experts in design who have been taught the proper methods for eliminating radon and other hazardous gases from the home, as discussed in the NKBA Professional Resource Library volume Kitchen and Bath Systems (NKBA.org/Books). In addition to radon, NKBA-certified designers are familiar with many other health concerns in kitchen and bath remodels that most consumers have never considered. Local AKBDs, CKDs, CBDs, and CMKBDs can be found by using the "Find a Professional" tool located at NKBA.org/Consumers.
For more details on the health effects of radon in granite countertops, the NKBA recommends the Marble Institute of America (MIA) as a reliable source of information. An associate member of the NKBA, the MIA has prepared a thorough analysis of radon levels and granite in its 2008 Radon Study. This study, as well as a consumer radon brochure and additional documents concerning radon in granite countertops are available at www.marble-institute.com.
