residency in home

Ruth #1,

I agree that residency in the home is very important.

That is one reason I like the Iowa Study. The median time the

subjects spent in their current home was over 30 years and at least

20 years. They also weighted their exposure estimates by the time

spent in the home.

This is from their website:http://www.cheec.uiowa.edu/misc/radon.html

1. Can you give us a short overview of the Iowa Radon Lung Cancer

Study?

The Iowa Radon Lung Cancer Study was a large-scale epidemiology

study, funded by the National Institute of Environmental Health

Sciences that assessed the risk posed by residential radon exposure.

The study was performed in Iowa and the participants were women

throughout Iowa who lived in their current home for at least 20

years.

3. Why was the study performed in Iowa?

The study was performed in Iowa for several reasons. Iowa has the

highest average radon concentrations in the United States. In

addition, women in Iowa tend to move less than most other states,

which makes calculation of their past radon exposure easier. Iowa was

also selected because it has a quality cancer registry, which helped

us identify women who developed lung cancer.

5. Why were only women selected for the study?

The study was limited to women, because they historically tend to

spend more time at home and they have less occupational exposure to

other lung carcinogens.
