The paper presents the dose mapping of the panoramic 60 Co gamma irradiation facility at
the Ruđer Bošković Institute in Croatia. Both experimental (using ionisation chamber) and
simulation (using the Geant4 Monte Carlo code) studies have been performed and
compared. Measured and simulation dose rates are found to be in very good agreement and
can be used for the absorbed dose determination in the irradiation chamber in everyday
work. In order to get a complete description of the dose distribution in the facility, the transit …
