Radiation Carcinogenesis and the Hair Folliclent and followed for long periods of time. The fact that rodent skin has been widely utilzed for testing carcinogenic chemicals permits comparisons of carcinogenesis by radiation and chemicals. The skin of albino rats responds to the carcinogenic action of several known human carcinogens, including, ionizing radiation and ultraviolet light.

Follow-up Studies of Patients Treated by X-Ray Epilation for Tinea Capitisvalent in low socioeconomic groups (1). In the United States, tinea capitis was relatively uncommon until a major epidemic occurred throughout the country during World War II (2). Treatment for ringworm of the scalp by X-ray epilation was introduced by Sabouraud in 1904 and standardized by Kienbock

Dose-Response for Radiation-Induced Cancer in Rat Skinrelatively easy to manipulate, and tumors are detectible at earlier times. The skin contains a comparatively large variety of cell types many of which are susceptible to the action of carcinogens. For example, rat skin exposed to radiation develops a variety of tumor types including, squamous carcin

Experimental Radiation Carcinogenesis more precise knowledge of the shapes of the dose-response functions. This knowledge is not available at present and is not likely to be obtained in the near future by direct observations. Two features of the dose-response relationships are most important for risk evaluation at low doses: the existe
