In attempting to extend the pioneer studies of Furth (1) and others on radiation carcinogenesis in mice, we have used a number of experimental approaches. Variationin total radiation dose, dose rate, dose fractiona-tion, and quality of radiation (for ex-ample, neutronsas compared with xrays) have all been investigated as well as the effect of proliferative stimuli applied to certain target organs before and after irradiation. It has be-come increasingly apparent that such relatively simple concepts as dose-re-sponse curves (2) or" initiation" by a carcinogenic agent and" promotion" by a noncarcinogenic stimulus (3), while useful, are not adequate to ex-plain some of the observed results. We have therefore proposeda conceptual sequence of events in radiation carci-nogenesis, attempting to incorporate many of the complex interactions which appear to operate at the subcellular, cellular, and whole-animal levels. In the present article, this out-line is presented, and certain points are illustrated byresults of our recent experimental studies. We recognize that many of the concepts offered are not original and that manyof the assump-tions are not universally accepted (see 4). The chief purpose in present-ing this scheme is to combine in a unified theoretical framework certain aspects of the problem of radiation carcinogenesis which appear not to have been generally recognized and to indicate areas which warrant further exploration.
