title: A comparison of human- and headform-based measurements of solar ultraviolet B dose.
abstract: New data on the distribution of solar ultraviolet B (UVB) radiation on the face are presented. Measurements made on human subjects and on rotating headform models are compared, and the effect of altering the orientation of the headform is considered. For a range of postures (standing, sitting, bending, kneeling) a corresponding headform angle (20 degrees, 30 degrees, 40 degrees, 60 degrees respectively) is determined that gives improved agreement with human-based measurements. This suggests that a more realistic simulation of human exposure is achieved by appropriately tilting the model.
