The aims of this study were to investigate how glass‐filtered UV irradiances vary with glass thickness, lamination of the glass and the effect of solar zenith angle (SZA), and to measure the glass‐filtered UV exposures to different receiving planes with a newly developed UVA dosimeter. Spectroradiometric and dosimetric techniques were employed in the experimental approach. The percentage of the glass‐filtered solar UV compared to the unfiltered UV ranged from 59% to 70% and was influenced to a small extent by the glass thickness and the SZA. The laminated glass transmitted 11–12% and the windscreen glass transmitted 2.5–2.6%. The influence of the SZA was less for the thicker glass than it was for the thinner glass. The change in transmission was less than 14% for the SZA between 48° and 71°. There was a negligible influence due to the SZA on the glass‐transmitted UV of the laminated and windscreen glass. The influence of the glass thickness in the range of 2–6 mm on the percentage transmission was less than 16%. The influence of the glass thickness and the SZA on the glass‐transmitted UV has been incorporated in the use of a UVA dosimeter for the glass‐transmitted UV exposures. The UVA dosimeter was employed in the field to measure the glass‐filtered UV exposures to different receiving planes. The UVA dosimeter has the potential for personal solar UVA exposure measurements.
