William Angell's (Housing Studies) paper entitled "The US radon problem, policy, program and industry: achievements, challenges and strategies" is currently the top paper published in the field of radon over the past three years.
The paper documented that the number of U.S. homes with elevated radon increased about one-third over the past 20 years because the number of newly built homes elevated in indoor radon exceeded the number of elevated existing homes which were mitigated. The findings presented in the paper were cited in a U.S. Inspector General's report critical of the lack of progress in the Environmental Protection Agency's radon program. The findings have also supported the President's Cancer Panel's 2010 recommendations for expansion of renewed efforts to pass building code requirements for new residential buildings and to expand increased radon mitigation.
