Abstract

Exposure measurements of global solar ultraviolet radiation (UV) with two types of dosimeters are compared in this evaluation: polysulphone badges with plastic film that changes its transmission after UV-exposure, and dosimeters which function by UV-induced DNA-damage to dried bacteria spores. The dosimeters agree well and are sufficiently precise. They agree also with data of daily global solar UV by two services (the European Commission's Joint Research Centre "JRC" and the Swedish Meteorological and Hydrological Institute "SMHI") which provide maps with radiation transfer (RT) model calculations of UV-exposures on a horizontal surface based on actual weather and ozone parameters from satellites. For full day exposures the two model calculations agree with each other too, and with results from a UV-monitoring instrument. Results of personal UV-exposure measurements with the two types of dosimeters do not need to be corrected. The JRC-model was better suited to calculate percentages of global UV during outdoor stay due to it's higher spatial and temporal resolution.
