Data from English radon study

[Bernard L Cohen <blc+@pitt.edu>]

The following are data from the English radon study. The first line is the
range of radon levels in Bq/m3. They give two treatments  which have the
results shown in the following two lines.In these, the upper number is the
ratio of observed to expected lung cancers, and the numbers below in
parentheses are the 95% confidence limits on these. The final line is what
they call the "mean radon level adjusted for uncertainties"; it is what
they use as the abscissa in their plots.
