minimal erythema dose

MED

actinic dose, using the erythema spectral weighting function, that produces a just noticeable actinic erythema on a single individual's previously unexposed skin

Note 1 to entry: The minimal erythema dose is a subjective measure based on the reddening of the skin; it depends on many variables, e.g. individual sensitivity to ultraviolet radiation, radiometric characteristics of the source, skin pigmentation, anatomic site, elapsed time between irradiation and observation of the reddening (typical value: 24 h). Since the minimal erythema dose varies with each individual, the use of this quantity should be reserved solely for observational studies in humans and other animals.

Note 2 to entry: See also "standard erythema dose".

Note 3 to entry: The minimal erythema dose is expressed in joule per square metre (J·m−2).

Note 4 to entry: This entry was numbered 845-06-24 in IEC 60050-845:1987.

Note 5 to entry: This entry was numbered 17-782 and 17-759 in CIE S 017:2011.
