Review of Scientific Instruments, 1948
A glow tube with thorium electrodes can be used to measure the intensity of ultraviolet light. The simple circuit used for this purpose does not give reliable results for photo-currents below 10−10 amp., and the exposure time to light may become several hours. The writer has devised certain improved methods which can measure small photo-currents of the

Experimental Ultraviolet Carcinogenesis
1993Much of our information on UV carcinogenesis has come from investigations carried out in animal models. Skin cancers have been induced experimentally with UV radiation in a variety of laboratory animals, including mice, rats, guinea pigs, and opossums.
