Abstract
The attenuation in ordinary concrete of the total dose equivalent due to ne utrons produced by 710 MeV alpha-particles on steel and water and by 337-39 0 MeV/u Ne ions on Al, Cu and Pb was calculated with the FLUKA Monte Carlo code. Experimental data (taken from the literature) of the neutron double d ifferential distributions were utilized for the source in the calculations. The contribution of all secondaries (neutrons, photons and protons) produc ed in the concrete shield was considered. Source terms and attenuation leng ths are given as a function of energy and emission angle. (C) 1999 Elsevier Science B.V. All rights reserved.
