Epilaiton and Hair Greying in Hamsters Following one Single Application of Beta Rays**From the Eppley Institute for Research in Cancer, 42nd and Dewey Avenue, Omaha, Nebraska 68105.

Abstract

Syrian golden and white hamsters were exposed to a single application of beta rays from a Krypton85 source in doses of 2,000, 4,000 and 10,000 rads. Permanent epilation was observed in Golden hamsters receiving the highest dose, permanent graying of hair was observed in lower doses. In white hamsters, permanent epilation occurred at lower doses than those for golden hamsters. Intense atrophy of the epidermis was observed histologically in animal's skin exposed to highest doses. A relatively higher mortality rate was observed in animals receiving higher doses of radiation. No spreading of the hair-greying effect of beta rays was observed in this experiment
