Radon Tee: World Trek 2010 Interview, WHAS11 News

My first interview of 2010! I appeared on WHAS 11 with my manager to discuss the importance of testing your home for radon. Watch the interview

I'll be appearing a few more times this coming week...stay tuned!

Will Radon Leaders Ski Tahoe this winter?

Radon Leaders at the EPA should be aware that Lake Tahoe is classified as a moderate radon region on the Official (but old) EPA Radon Map while the recent California Geological Survey radon map of Tahoe shows a "very high" radon potential. Since building departments, real estate hazard reports and even USGBC's LEED green building certification program uses the old EPA radon map, little is required in the way of radon mitigation in this high radon area. The Sierra Green Building Association (SiGBA) ran my article on the "radon map problem" in their recent newsletter:


Either LEED, the National Association of Realtors, and local building departments should use more local, recent and accurate radon maps or the EPA should update their old-and-in-the-way national radon map. So far, it's easier to use inaccurate data than change the system.

Housing-Radon Data

Per EPA’s contract with the NAHB-Research Center, the radon data from their 2008 membership survey is in.

1-Nationally an estimated 539,000 SFH were built; 66,000 (12.2%) of them included radon-resistant features. Although the absolute number of RRNC homes decreased significantly (109,000 down to 65,700), the percentage increased, from 11.8% in 2007 to 12.2% in 2008.

2-In Zone 1 an estimated 133,100 SFH were built; 41,200 (31%) of them included radon-resistant features. Although the absolute number of RRNC homes decreased significantly (62,900 down to 41,200), the percentage increased, from 28.6% in 2007 to 31% in 2008.

In the wider housing market, NAHB/Commerce Dept. reported today that:

1-sales of newly built homes declined 11.3% in November to an annual rate of 355,000 (compare that to the 539,000 in 2008).

2-sales of new SFH declined in 3 of 4 regions (Northeast by 3.3%, South by 21.1% and in the West by 9.2%); sales rose by 21.4% in the Midwest

EPA Announces $2 Million CARE RFP (NOFA)

EPA $2 Million CARE RFP (NOFA)

EPA is making $2 million available in 2010 to reduce pollution at the local level through the Community Action for a Renewed Environment (CARE) program. CARE is a community-based program that works with county and local governments, tribes, non-profit organizations and universities to help the public understand and reduce toxic risks from numerous sources. Since 2005, the grants have reached 68 communities in 34 states and territories. A recent evaluation by the National Association of Public Administration (NAPA) recognized the CARE program as a solid tested framework for engaging communities and other stakeholders.

Green radon mitigation systems

I am interested if any one has created a radon mitigation system that is powered by solar or wind.

Active RRNC Model Code Proposal

Announcement - December 11, 2009

This is an announcement for a new effort to develop an ANSI/AARST model code for Active Radon Resistant New Construction (Active RRNC) in high radon areas. This new model code is intended to support code change proposals under consideration in the International Residential Code (IRC). Modifying the building code to require an Active Soil Depressurization (ASD) system in all new homes in high radon areas in the United States will further the joint goals of the Environmental Protection Agency (EPA), Conference of Radiation Control Program Directors (CRCPD) and the American Association of Radon Scientists and Technologists (AARST) to double the radon mitigation rate in the United States over the next five years.

Radon is a colorless and odorless radioactive gas that is produced by the radioactive decay of radium. Radium is a product of uranium decay and is found in trace amounts naturally in nearly all rocks, soils, and groundwater as well as building materials, plants, animals, and the human body. Radon concentration is expressed as the amount of radiation that would be emitted by radon and its decay products in a liter of air; thus the units are picocuries per liter (pCi/L). The American Cancer Society, on its Web site, states that the estimates for lung cancer deaths caused by radon each year is between 15,400 and 21,800.

ICRP Radon Statement

ICRP has recently released an updated statement on radon that generally fits well with the recent WHO guidance. See : http://www.icrp.org/icrp_radon.asp
