SKIN REACTIONS TO SIMULTANEOUS TREATMENTS WITH RADIANT HEAT AND SOFT X-RAYS

Abstract
Guinea pigs have been exposed to suberythema doses of soft x-rays, to radiant heat of intensity about critical for producing slight burns, and to both radiations simultaneously. No erythema was produced in the skin of the animals exposed to x-rays alone and only slight burns resulted in 50 per cent of the animals exposed to heat radiation alone. The animals exposed to heat and x-radiation simultaneously developed well marked burns which healed much more slowly than those produced by heat alone.
