Effects of Dose Fractionation on the Response of Alanine Dosimetry



Marc F. Desrosiers, John Logar, Brad Lundahl


Alanine dosimetry is well established as a transfer standard and is becoming more prevalently used as a routine dosimetry system for radiation processing. Many routine measurement applications in radiation processing involve absorbed dose measurements resulting from fractioned exposures to ionizing radiation. Absorbed dose fractionation is identified as an influence quantity (ISO/ASTM, 2013) and may affect the response of a dosimeter. This paper reports on study results of absorbed dose fractioning characteristics of alanine for gamma and high energy electron beam radiation sources. The results of this study confirm that dose fractionation affects the response of the alanine dosimetry. The response difference was observed at the four faction level for the high-energy electron beam and up to seven fractions for gamma rays.
