“…Although UVB represents less than 1 % of the total energy of the solar spectrum reaching the earth's surface, the high energy in each quantum at these short wavelengths damages some of the most important biological processes, the principal target being the DNA molecule (Jagger 1985), although protein damage also occurs (Hader 1997).…”

This paper examines the potential of polysulphone film (PSF) as a dosimeter for unweighted solar ultraviolet-B radiation (UVB; 280 to 320 nm) in different seawater conditions in tropical latitudes. PSF's accuracy is determined by water type and depth range. The film may be used over a depth range of 7 m with measurement errors of less than 5 % in oceanic type waters, such as are found around coral atolls and islands. In clear but coloured continental coastal waters the range decreases to 2.2 m. Calibration functions are presented for use of the film both in air (e.g. an intertidal setting) and underwater over the UVB dose range of about 1.5 to 40 kJ m-' A comprehensive analysis of errors arising from the use of PSF, in air and underwater, is given. The film offers a cost-effective and simple technique for studying biological responses to solar UVB radiation in many tropical marine habitats, including intertidal and subtidal coral reefs.
