I hate this image so much because it implies that neutron radiation has more penetrating power than gamma when it’s actually because different things stop them and it’s entirely energy dependent on what that is. You could stop neutrons with a slab of hydrocarbons that gamma would blast right through.
To be fair neutrons are usually harder to block. Lead has a tenth thickness of 2” for gammas whereas the smallest tenth thickness for neutrons is around 6” for borated poly and the most common shields are water at 10” and concrete at 14”
So yeah it is different but overall it takes much thicker shields to block neutrons than gammas
