Polysulphone dosimeters using a simple to use filter have been developed and tested to provide an extended dynamic measurement range of personal solar W exposures over an extended period (3 to 6 days). At a Southern Hemisphere subtropical site (27.6°S, 151.9°E), the dynamic range of the filtered polysulphone allowed measurements of erythemal exposures to approximately 100 minimum erythemal dose (MED) for a change in optical absorbance at 330 nm (AA 330 ) of 0.35. In comparison, unfiltered polysulphone dosimeters were exposed to approximately 8 MED for the same AA 330 . The error associated with the use of the filtered polysulphone dosimeters is of the order of ±15%, compared with ±10% of the unfiltered variety. The developed filtered polysulphone dosimeter system allowed the measurement of erythemal UV exposures over 3 to 6 days at a subtropical site without the need to replace the dosimeters because of saturation. The results show that longer‐term measurement programs of personal solar UV have been made more feasible with the use of these polysulphone dosimeters with an extended dynamic range compared with unfiltered polysulphone dosimeters.
