Attix free-air chamber correction factors computed using EGSnrc. [PDF]
Med PhysAbstractBackgroundA cylindrical free‐air chamber, the Attix FAC, is used for absolute air‐kerma measurements of low‐energy photon beams at the University of Wisconsin Medical Radiation Research Center. Correction factors for air‐kerma measurements of specific beams were determined in the 1990s.
