155/157Gd areal density A model for design and
The Monte Carlo N-Particle Code were used to design a novel Gd 2 O 3 /316L stainless steel neutron shielding composites (Gd 2 O 3 /316L NSCs). And the constitutive equation between the 155/157 Gd areal density and the neutron shielding rate was established by MCNP. When the areal density of 155/157 Gd is larger than 0.01 g/cm 2 the thermal neutron shielding rate of the composites reaches

On the other hand if a ping pong ball is thrown against a bowling ball (neutron vs. heavy nucleus) the ping pong ball will bounce off with very little change in velocity only a change in direction. Therefore lead is quite ineffective for blocking neutron radiation as neutrons are uncharged and can simply pass through dense materials.
