Assessment of dose measurement uncertainty using RisøScan

The dose measurement uncertainty of the dosimeter system RisøScan, office scanner and Risø B3 dosimeters has been assessed by comparison with spectrophotometer measurements of the same dosimeters. The reproducibility and the combined uncertainty were found to be approximately 2% and 4%, respectively, at one standard deviation. The subroutine in RisøScan for electron energy measurement is shown to give results that are equivalent to the measurements with a scanning spectrophotometer.
