ABSTRACT
Extensive works have been published on the effect of ionizing radiation on the skin. In fact, the first effect of ionizing radiation appeared as an acute radiation dermatitis, or so-called “radium burn,”among investigators working with radium. Prior to the introduction of “R”as a measurement of radiation exposure, radiation therapists utilized skin reaction — which they referred to as the threshold erythema dose (TED) — as a measurement of radiation dose.
