A new photobiological term, the mean exposure fraction (MEF) is introduced in this research. The MEF is calculated for erythemally effective UV exposures to unprotected skin surfaces of an upright life-size body manikin. The MEF can be weighted with measured or modeled horizontal plane ambient erythemal UV exposures to determine total body weighted exposure where no or limited body site exposure information is available. The MEF is presented for the SZA ranges 0°–30°, 30°–50° and 50°–80°.
