ALANINE DOSIMETRY OF 60 MeV PROTON BEAM - PRELIMINARY RESULTSBarbara Michalec, Gabriela Mierzwińska, Urszula Sowa, Marta Ptaszkiewicz, Tomasz Nowak, Jan Swakoń Proton Radiotherapy Group, The Henryk Niewodniczański Institute of Nuclear Physics, Polish Academy of Sciences, 152 Radzikowskiego Str., 31-342 Kraków, Poland Electron paramagnetic resonance (EPR) spectrometry (X-band) was used to determine the dose absorbed in alanine detectors, of different shapes and different alanine content, irradiated with Co-60 gamma rays and in a 60 MeV proton beam. The goal of our study was to confirm applicability of alanine as a passive detector in therapeutic proton beam. In the paper dose response characteristic and relative efficiency of alanine are shown. The study confirmed that alanine detectors with a high alanine content (ca. 95%) may be a useful and convenient tool for dose measurements in proton beams, used for eye cancer treatment. Close X |
