Abstract
The alanine dosimetry system is now preferred by all primary and secondary calibration laboratories for their high-dose ionizing radiation calibration services. Alanine dosimeters in the form of cylindrical pellets have been available in commercial quantities for several years. Despite their high quality, the physical dimensions of the dosimeter were not suitable for many electron-beam processing dosimetry applications. Alanine in the form of a thin-film would be more appropriate for electron-beam applications. However, a reliable manufacturer/supplier for high-quality alanine film dosimeters was lacking. To fill this void Bruker BioSpin and Kodak have teamed up to successfully develop an alanine film dosimeter that appears to have excellent dose measurement properties in a highly robust form. Described here are the characterization studies for this new dosimeter that assess the effects of relative humidity and the post-irradiation temporal stability of the alanine film dosimeter.
