In the 1920s-1940s there was considerable scientific work on the effects of ionizing radiation to induce mutations, originally come out of work by H.J. Muller on fruit flies (for which he won the Nobel Prize in Medicine for 1946), but later expanded to all sorts of agricultural breeding programs. It isn't, of course, that radiation makes things necessarily bigger or anything like that, but it can increase the number of mutations far above the normal rate. If you irradiate thousands of fruit fly eggs, you'll end up with a few very bizarre specimens as a result (e.g., flies born without eyes, flies born with weird wings, whatever).
