Calibration of installed dose monitors measuring the ambient dose equivalent, H * (10), should be done periodically according to portuguese national law. These monitors are fixed on the wall of the facility, hospitals or any other installation and usually they are checked in situ . To be able to realize this calibration LMRI (Metrology Laboratory for Ionizing Radiation) constructed a portable irradiator made of lead with a 137 Cs source. The dosimetric characterization of the irradiator was realized and the H * (10) was determined at several distances from the irradiator. The profiles at different distances from the irradiator have been performed either experimentally or using the MCNPX code and was observed that the full width at half maximum of the radiation field is a linear function of the distance to the irradiator. The influence of the wall where the monitors are installed was studied by Monte Carlo simulation and correction factors applied to the H * (10) are determined.
