Ultraviolet exposure to children from sunlight: a study using personal dosimetry.
Childhood exposure to ultraviolet (UV) radiation in sunlight may be an important risk factor for later development of skin diseases. We quantified the UVB radiant exposure on the wrist and face of children performing mixed outdoor activities at a summer camp. Polysulfone film badges were attached directly to the skin for several hours and simultaneously were used to measure ambient UVB levels. The results for the ratio of site-specific exposure to ambient exposure indicate a high degree of intersubject variability, a parity of samples taken in right and left positions, and a significantly higher exposure on the wrist compared with the face. The technique was well accepted by the subjects but some badges could not be read because of loss or damage. Measurement of exposure ratios in additional settings as well as data on childhood activity patterns are needed for an overall assessment of childhood exposure.
