What you should know about Radon
Radon is a radioactive gas that can cause lung cancer.
The EPA ranks indoor radon among the most serious environmental health problems facing us today. After smoking, it is the second leading cause of lung cancer in the United States causing an estimated 23,000 lung cancer deaths a year. It is the leading cause of lung cancer among non-smokers.
Residential Testing:
For Home Owners: Following the EPA protocols for radon and radon decay product measurements in homes
For Home Buyers: Following the EPA Protocols for radon & radon decay product measurement in homes during a real estate transaction
Radon in Well Water: Following the EPA Protocols and CT DPH for testing well water for Radon. Sampling & analysis technic.

Testing in Connecticut Public Schools:
As required by Connecticut General Statute 10-220(d):
All Connecticut Public Schools are required to be tested for Radon every 5 years. The first cycle commenced in 2003 and ended on January 1, 2008. We are now in the next 5 year cycle. Contact us to comply with this second cycle of testing CT public schools!

Concerns about Radon from Granite Countertop:
Recently there has been much press about granite countertops emitting radon into the indoor air in the home. As every home should be tested for radon in general, if it is a concern when you have granite countertops, the EPA Protocols should be followed for testing the home and an area near the countertops can be tested at the same time to compare the results. AARST has developed a protocol to follow if this is a concern. Call us for further details or to have your home tested.

Independent Analysis Shows Granite Countertops Pose No Health Risk
First published, peer-reviewed studies of the impact of emissions from granite countertops on human exposure find granite safe for indoor use.

CLEVELAND, Aug. 31 /PRNewswire/ -- Two new studies published in the scientifically peer-reviewed Journal of Exposure Science and Environmental Epidemiology show that granite used in countertops poses no radon or radiation threat to consumers.

"Based on the results of our research, we did not identify any slabs of granite intended for sale as countertop that would produce exposures that exceed health-protective limits or background levels commonly found in the environment," said Dr. Joseph G. Allen, of Environmental Health & Engineering, Inc., a principal investigator in both studies.

The science behind the studies was rigorously reviewed by independent scientists at the request of the Journal to ensure the studies are valid and used appropriate scientific methodology. Statements made by critics of granite countertops have not undergone this peer-review process.

The studies, published in the August 26, 2009 online issue of the Journal, conclude:

The market share-weighted average concentration of radon in indoor air attributable to emissions from granite countertops was estimated to be about 400 times lower than the action level recommended by the EPA.

Typical granite stones are likely to be a minor source of radiation dose when used as a countertop material within the home and present a negligible risk to human health.

Critics of granite have suggested that granite countertops pose significant health risks. However, after a year of claiming to have scientific proof, no study has been published by a scientific, peer-reviewed journal that demonstrates a meaningful environmental exposure resulting from granite countertops.

"We have repeatedly asked critics to share their specific findings with us, so that we can determine if any real risk exists," said Guido Gliori, president of the Marble Institute of America, the nation's leading natural stone trade organization. "Some have simply rejected our requests, others have said they will share findings once their studies are published. In the meantime, Environmental Health & Engineering conducted an independent assessment of granite that went through rigorous scientific peer review and now has been published. Meanwhile, we're still waiting for critics to share any real information."

The abstracts of the two studies, "Assessing exposure to granite countertops - part 1: Radiation" (Journal of Exposure Science and Environmental Epidemiology [26 August 2009] doi:10.1038/jes.2009.44) and "Assessing exposure to granite countertops - part 2: Radon" (Journal of Exposure Science and Environmental Epidemiology [26 August 2009] doi:10.1038/jes.2009.43) are available at http://www.marble-institute.com/, the Marble Institute of America's website, with links to the Journal's website, http://www.nature.com/jes/index.html.

The Journal will publish the studies in its printed version later this year.
