> May 17, 2002 - Ascribe News (05/16/02) - University of Iowa Study Finds

> Health Risk From Residential Radon Exposure Higher Than Previously

> Estimated - The health risk posed by residential radon exposure may have

> been substantially underestimated in previous studies, according to

> investigators in the University of Iowa College of Public Health. Long-term

> exposure to radon gas in the home is associated with increased lung cancer

> risk and presents a significant environmental health hazard. "Our findings

> indicate that the exposure assessment models used in many previous studies

> may have underestimated the risk posed by residential radon exposure by 50

> percent or more," said lead author R. William Field, Ph.D., a research

> scientist with the UI Department of Epidemiology. The results of the study

> appear in the May 2002 issue of the Journal of Exposure Analysis and

> Environmental Epidemiology. The UI researchers examined several exposure

> assessment methods used by previous residential radon studies performed in

> North America, Europe and China. They compared these models to a more

> comprehensive exposure method that linked a person's movement to various

> radon measurements within a home. All of the models were assessed using the

> same study population. The exposure methods used by previous studies all

> produced lower risk estimates than the comprehensive method. The highest

> degree of error was noted for methods that based risk solely on basement

> radon measurements. "While radon concentrations tend to be highest in

> basements, people typically spend limited time there," Field said. "A more

> accurate assessment of risk can be formulated by linking multiple radon

> measurements taken within a home to where and how much time an occupant

> spends in the home."
