  1. 6. Characterization of the 60Co therapy unit Siemens Gammatron 1 using BEAMnrc Monte Carlo simulations

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Sandro Carlos De Luelmo; [2006]
    Keywords : 60Co; Monte Carlo-simulation; Siemens Gammatron 1; Latch; 60Cobalt-spectra;

    Abstract : The aim of this work is to characterize the beam of the 60Co therapy unit “Siemens Gammatron 1”, used at the Swedish Radiation Protection Authority (SSI) to calibrate therapy level ionization chambers. SSI wants to know the spectra in the laboratory’s reference points and a verified, virtual model of the 60Co unit to be able to compare current and future experiments to Monte Carlo simulations.
