Dr. Seiler,

The information you requested is in Table 5.  It clearly shows a
statistically
sigificant excess odds ratio at 100 Bq/m3 for homes monitored over 10 years.

As pointed out in the paper, "Field et al. have recently demonstrated that
empiric models with improved retrospective radon exposure estimates were
more
likely to detect an association between prolonged residential radon
exposure and lung cancer."

Further, "Odds ratios exhibit no apparent evidence of nonlinearity
throughout the range of radon concentrations observed
in these studies."

If you or Dr. ALvarez have any concerns about the analysis or its
inperpretation, we would welcome a letter-to-the-editor regarding your
concerns. 

Regards, Bill
