At the International Workshop on Biological UV-Dosimetry in Budapest,
29 November-3 December 1994, a comparison of different UV-dosimeters w
as carried out in order to evaluate their performance and to compare d
ifferent types of measurement. The various dosimeter types included do
tted dried spores of Bacillus subtilis on glass and plastic (''biofilm
s''). Solar Light Company Biometers (Robertson-Berger Meters), thin la
yer uracil sensors, and several handheld electronic devices. An electr
onic dosimeter (ELUV-11) designed as a button to wear on clothing also
took part in this intercomparison. In the following, data obtained du
ring the ELUV-11 measurements is presented, and properties of this cla
ss of personal dosimeters are discussed.
