Exposure to solar UVA (320–400 nm) radiation can damage DNA and lead to skin disorders. Conventional dosim‐etry using a single piece of polysulfone or diglycol carbonate (CR‐39) cannot provide accurate measurement of the biologically effective irradiance for erythema for the UVA waveband. A package employing four dosimeters (polysulfone, nalidixic acid, 8‐methoxypsoralen and phe‐nothiazine) has been shown to be effective for use as a spectrum evaluator for evaluating the UVA source spectrum. In Brisbane, on a horizontal position, the spectrum evaluator requires about 5 min exposure in summer and about 20 min in winter. This amounts to about 10 mJ cm‐ 2 of erythemal UV radiation.
