Standard erythema dose
WebbRecently the term minimal erythema dose (MED) has been used widely as a 'measure' of erythemal radiation. This is unreasonable because the MED is not a standard measure of anything but, on the contrary, encompasses the variable nature of individual sensitivity to ultraviolet radiation. WebbThe standard erythema action spectrum provides an internationally accepted representation of the erythema-inducing effectiveness of wavelengths in the UV part of …
