In recent years, the residential exposure to radon daughters has become a
cause for concern as a contributing factor for lung cancer. In order to
evaluate the population's risk consequences of different interpretations of
the results of epidemiological studies in cohorts of uranium miners, a
simulation model has been formulated. In the model, a defined population is
generated as a set of individuals with a distribution of characteristics
and exposures as they are known to exist in the defined population. The
risk for each individual of being diagnosed with lung cancer in the next
year can be determined, based on whatever interpretation is being
evaluated. The risk can then be translated into an annual number of cases,
and suitable controls can be identified as well. Both cases and controls
have their individual risk factors of radon daughter exposure and history
of cigarette smoking, and it is possible to subject these cases and
controls to statistical analyses appropriate to case-control studies. This
analysis can be used to see to what extent the original risk equation can
be retrieved, and to what extent other risk formulations can be rejected.
The simulation model can be used to evaluate conclusions drawn from prior
epidemiological studies, as well as for evaluations of the effectiveness of
designs for proposed studies.
