English Radon Study

[Joyce Davis <JOYCED@DNFSB.GOV>]

The June Issue of Nuclear News (pg 18) has an item
reporting  as follows:  
An increased risk of lung cancer from Radon in the home
appears to be confirmed by a large epidemiological
case-study of people living in southwest England....  The
latest study reported in the June issue of the British Journal
of Cancer  was undertaken by the Imperial Cancer Research
Fund ....   The study concludes that the estimated relative
risk associated with a 100 Bq m(-3) increase in residential
radon concentration is 0.08  (with a 95 percent confidence
interval of -0.03 to 0.2).

Can anyone supply more information about this study ?  Did
it account for smoking habits ?
