| چکیده | ||
| In this work we calculated neutron dose buildup factor at energy interval 80-120 MeV for the calcareous type of ordinary concrete (i.e., one made of sand and aggregate composed basically of limestone) by using the data from the literature and an improved empirical fitting formula for estimating neutron buildup factors. We could estimate the removal macroscopic cross section of neutron (ƩR) in this range of energy (80-120 MeV) at various mass thicknesses (0˂X˂550) for this type of concrete. The results are compared with the Monte Carlo method. | ||
