Proceedings of a Meeting Organized Jointly by the IAEA and the ICRU held in Ohio, USA, 18–20 March 2006 IAEA TECDOC No. These coefficients were calculated using the official ICRP/ICRU computational phantoms representing the Reference Adult Male and Reference Adult Female, in conjunction with Monte Carlo codes simulating the transport of radiation within the human body such as EGSnrc, FLUKA, GEANT4, MCNPX, and PHITS. Cell and Molecular Biology A nationally leading academic research center of high international standard where science comes first and foremost. Based on microdosimetry considerations [ICRU, 1983], cellular survival versus dose of low-LET (X-ray) radiation became described by an exponential expression with terms linear and quadratic with dose (the so-called “alpha-beta” or linear-quadratic description), where a purely exponential survival (with an “alpha” term only) dose.
