[ 1 ] - An Efficiency Studying of an Ion Chamber Simulation Using Vriance Reduction Techniques with EGSnrc

Background: Radiotherapy is an important technique of cancer treatment using ionizing radiation. The determination of total dose in reference conditions is an important contribution to uncertainty that could achieve 2%. The source of this uncertainty comes from cavity theory that relates the in-air cavity dose and the dose to water. These correction factors are determined from Monte Carlo calcu...
