Abstract
The neutron Howitzer container at the Neutron Measurements Laboratory of the Nuclear Engineering Department of the Polytechnic University of Madrid (UPM), is equipped with a 241Am-Be neutron source of 74 GBq in its center. The container allows the source to be in the irradiation and storage position. To measure the neutron fluence rate spectra around the Howitzer container, measurements were performed using a Bonner spheres spectrometer and the spectra were unfolded using NSDann program. A calibrated neutron area monitor LB6411 was used to measure the ambient dose equivalent rates, H ?*(10). Detailed Monte-Carlo simulations were performed to calculate the measured quantities at the same positions. The maximum relative deviation between simulations and measurements was 19.53%. After validation, the simulated model was used to calculate the equivalent dose rate, H ?T, in several key organs of a reference man voxel phantom. The computed H ?T in the skin and lenses of the eyes are within the ICRP recommended dose limits, as is the H ?*(10) value for the storage position
