Abstract— Design, construction, and testing of a photoelectronic UV‐B personnel dosimeter whose optical system and thus wavelength and angular response match closely the Robertson‐Berger sunburn ultraviolet meter is described. Erythemal irradiance is sensed by a MgWO 4 fluor, and cumulative exposure is stored in digital form by custom‐built hybrid microcircuits for readout through a microcomputer at a central station or a field display unit. Sensitivity and exposure storage capacity are designed to provide research‐standard precision in measurements of a few hours to ∼ 2 months duration, and a high level of temperature stability has been achieved. The dosimeter's compactness, rugged and waterproof construction, and wide dynamic range make it applicable to laboratory and environmental photobiology research as well as in skin cancer epidemiology studies.
