Comparative measurements of solar UV radiation with spore dosimetry at three European and two Japanese sites

Spore dosimetry of solar UV radiation has been employed in several field in tercomparison campaigns carried out in summer months in Japan and Europe. T he dose-rate profiles, total daily doses and personal daily exposures have been determined and compared at five sites based on the spore inactivation dose (SID). The maximum dose rate (0.83 SID/min) and the maximum daily dose (197 SLD) observed at subtropical Naha (26.2 degrees N) are about three ti mes those observed at subarctic Abisko (68.4 degrees N). The amounts of per sonal exposure during three European campaigns are moderate and show a tend ency of inverse relationships with the daily doses. (C) 1999 Elsevier Scien ce S.A. All rights reserved.
