THE DEVELOPMENT OF PERSONAL DOSIMETERS FOR USE IN THE VISIBLE AND ULTRAVIOLET WAVELENGTH REGIONS

We have designed, developed, and field evaluated a two-part personal dosimeter for estimating ocular exposure to visible and ultraviolet radiation. The detector head is compact enough to be mounted on the bow of eyeglass frames, and the recorder is small enough to be carried in a shirt pocket. The detector head consists of a silicon photodiode with filter (Schott glass GG400) and diffuser for visible light measurements and a polysulphone film badge for ultraviolet-B (UVB, 290-320 nm) measurements. The measurements correspond well to those obtained using ambient monitors and should be useful for studies of ocular UVB exposure.
