MED

MED
   a common symbol for "minimum erythemal dose," the smallest amount of ultraviolet radiation that produces observable reddening (erythema) of the skin. (Skin is sensitive to reddening by radiation in only a narrow band of wavelengths around 300 nanometers.) The MED obviously varies from one person to another.
   Doctors and tanning salon operators typically use a value of 200 joules per square meter (J/m2), which represents the MED of a highly sensitive individual; persons with dark skin have MED's in the range of 1000 J/m2. Regulatory agencies are moving to use of the standard erythemal dose (SED), a unit equal to exactly 100 J/m2. In tanning, a dose rate of one MED per hour is equivalent to 55.55 milliwatts per square meter of skin surface.
