Av. Parisi et al., THE EFFECTS OF BODY-SIZE AND ORIENTATION ON ULTRAVIOLET-RADIATION EXPOSURE, Photodermatology, photoimmunology & photomedicine, 12(2), 1996, pp. 66-72
A method has been developed for determining the UV and erythemal expos
ures to the entire body. The difference between the ambient erythemal
exposure and that to the body compared to the ambient exposure may be
as high as 76%. The height, orientation, and overall height had a mini
mal effect on the exposure to the body with size, time of day and time
of year having a significant effect. The diffuse component of UV to a
side of the body ranged from 20% to 41% between different times of th
e year with different levels of cloud cover. The ratio of the body to
the ambient erythemal exposures varied from 0.24 to 0.61, with the tim
e of day and time of year with the smaller value for periods of high s
olar altitude.
