Do "Enhanced Radiation" nuclear weapons actually leave infrastructure usable?

So for decades, the concept of a “neutron bomb” has been trotted around many times. It’s commonly used to describe a device that you could set off over a city and kill the population while leaving their stuff intact and usable.

This is not true in any respect, right? Because reading about what a neutron bomb isand thinking about the effects, well :

It’s still a nuke. There’s going to be a huge blast and shockwave. Gonna be hard to use anyone’s stuff after it was all vaporized.

Even the area around the immediate blast, where the neutrons have hit everything, the reason to use neutrons is that it activates surrounding material, making it all radioactive.

The area damaged by a neutron bomb would thus remain uninhabitable, for possibly decades, because it’s all been neutron activated and also sprinkled with fallout.

Finally, the wiki article mentions that if specific metals were used in the bomb casing, it could make the area affected uninhabitable for a century from cobalt-60 contamination.

A nuke is a nuke, and anything close enough to the device is going to be completely destroyed. But not everything will be that close. A neutron bomb would in fact have a ring in which people were killed, but buildings are still mostly undamaged.

But that was never the purpose behind a neutron bomb. The main purpose was to increase the radius at which you could quickly neutralize an armored vehicle, like a tank. While a direct hit from any nuke will destroy a tank, just like it’ll destroy anything else, the insta-kill radius for a standard bomb will be fairly small against an armored vehicle, making nukes unsuitable for battlefield use. The solution was to produce a type of radiation which could penetrate a tank’s armor, but still kill the crew inside.

Actually, as most tanks have armor containing depleted uranium, the neutron flux from an ‘enhanced radiation’ weapon will activative it, causing it to fission and producting unstable isotopes and emit intense radiation on the occupants and render the vehicle unusable. It will do the same to other elements in the environment, creating a profusion of intense, short-lived radioactivity, acting as an effective area denial weapon but without the enormous thermal pulse and firestrorm produced by weapons from which the yield is primarily high energy ionizing radiation (X-rays and gamma rays). The radius of total destruction of such weapons is much smaller and the attendant effects outside that radius are lesser yet, such that reinforced buildings and infrastructure may remain mostly intact and can be used after the short period isotopes decay and the area is decontaminated.

However, the real purpose that enhanced neutron yield weapons were originally developeed for was as counterforce and terminal anti-ballistic missile (ABM) applications, using the neutron flux to prematurely activate and fizzle incoming weapons that were intercepted inside the atmosphere. The Sprint missile (the terminal interceptor component of the Safeguard ABM system briefly deployed in 1975 at Grand Forks AFB) had a neutron-enhanced warhead intended to disable incoming threats as a last ditch effort for RVs that were not intercepted by the longer range exoatmospheric LIM-49 Spartan interceptors which had a larger nuclear weapon with the more typical ionizing radiation yield.
