The GEANT4 simulation and results discussed in this report were initiated as a follow-up study associated with the Horizontal Bender fringe-field beam steering problems. In addition,concerns were raised that earlier studies of radiation induced beam dose and heating issues did not take the large fringe-fields into consideration. The new simulations including the fringe-fields indicate the radiation heating on the bender is much larger than the initial results and can limit the lifetime of the magnet if the operations are not properly metered.
