Abstract
Action spectra for transformation of human embryonic skin and muscle fibroblasts to anchorage-independent growth were determined. Tests under experimental conditions indicate that reciprocity holds for photon rate and exposure time and that all the dose-effect curves in the wavelength range of 248-297 nm are similar. These data can be used to construct action spectra with a maximum at .apprx. 265 nm, which do not implicate moieties other than nucleic acids as absorbers in the transformation process. [This data can be used to quantitate the oncogenic effects of sunlight on human cells.].
