Standard Absorbed Dose to Water for HDR Brachytherapy Sources with Fricke Dosimetry

Following the general trends of modern dosimetry the quantity absorbed dose in water is the one mostly needed in clinical practice. A few attempts have been reported to establish this quantity for HDR brachytherapy and potential good results of two novel techniques have been reported, firstly by Sarfehnia et al (2007) using a water based calorimeter and secondly by Austerlitz et al (2008) both with uncertainties still high, 5% and 8% respectively and deAlmeida et al (2008) with uncertainties smaller than 3% both using ferrous sulphate-Fricke dosimeter.
