A neutron bomb is a type of tactical nuclear weapon eveloped specifically to release a relatively large portion of its energy as energetic neutron radiation. This contrasts with standard thermo-nuclear weapons, which are designed to capture the intense neutron radiation inside the bomb to increase its overall yield. The technical term for the neutron bomb is "enhanced radiation weapon" (ERW). In terms of explosive yield, ERWs are about one-tenth that of a conventional fission type weapon. While significantly less in explosive power, they are still much more potent than any conventional bomb, so it should be understood damage to material is reduced and not eliminated.
