That's the idea behind fallout shelters and bomb shelters. Thick, strong reinforced concrete, or just a lot of earth. A basement with a solid floor above will protect you from any blast that's at least a mile or two away. A basement with a reinforced concrete roof brings that to a couple hundred feet. For protection at ground zero, you'd probably need to get 100 feet or so beneath the earth's surface. There's plenty of old Civil Defense literature telling you what survival materials you'd likely need, or just think what you'd need to survive in a closed, airtight room for a week, plus clothing that would cover you completely as you walk away through the radioactive debris.

If you are not too close, you can be protected from the blast and the radioactivity by underground shelters.

Alpha-, beta-, and gamma-rays are absorbed by mass. Mass/area is shielding. Neutrons are scattered by light nuclei and mostly ignore heavier nuclei. They can be stopped by resonant absorption - boron, cadmium, gadolinium; hafnium.

Yes, buildings and human bodies.
