INVESTIGATORS long have sought means of protection against harm from radiation. The threat of mass injury in the atomic age accentuates all the more the urgent necessity for this research. This form of physical energy characteristically penetrates the deeper parts of the body, yet the skin by its exposed position remains the organ of primary attack. The accessibility of the skin as a target and the simplicity of retrieving it for study are advantages favoring its use for experimental purposes. The dermatologist naturally has an interest in any cutaneous study; but. because he so frequently resorts to the use of radiation therapy, he pays inordinate attention to investigations in this realm of biophysics.
The literature covering this field of activity is becoming so large as to be beyond the compass of any except the specialist. A few samplings from it may be a shortcut to the point. Knowlton, Hempelmann, and
