title: Interaction of smoking and radon in rats: a biologically based mechanistic model.
abstract: Data on rats exposed to cigarette smoke before or after exposure to radon are used to estimate smoke-dependent parameters of the biologically based two-stage clonal expansion model. The baseline parameters and the action of radon acting on initiation and promotion were fixed based on earlier work. Cigarette smoke acting on transformation and inducing a reduction of the radon dose to the target cells after a smoking period gives an acceptable description of the data.
