Abstract
A simulation study of the Tunisian Gamma Irradiation Facility has been realized using GEANT Monte Carlo code of CERN. Dose rate was calculated and measured in air and in a "dummy" product inside the irradiation cell. Good agreement between experimental and calculation results was obtained and GEANT code is validated as useful tool to study Gamma Irradiation Facilities. (C) 2005 Elsevier Ltd. All rights reserved.
