Irradiation of mice with unfiltered FS40 sunlamps renders them susceptible to challenge with highly antigenic UV‐induced skin tumors. Dose‐response studies demonstrated that the susceptibility of mice to tumor challenge was directly proportional to the total dose of UV radiation, and was independent of the manner in which the dose was administered. A fractionated dose was no more effective than the same total dose given as a single treatment in inducing susceptibility to tumor challenge. The effects of even suboptimal doses of UV radiation persisted for as long as 6 months after the UV treatment.
