How much wall need to be thick to stop radiation and what material is used in that cases?

Suppose that are construction survive explosion that happen close by how much are concrete wall needs to be thick to prevent radiation from coming inside? I heard that reinforced concrete thick 5 meters can stop it.How much wall need to be thick to stop radiation and what material is used in that cases?
Alpha and beta cannot travel more than a meter in air..



Technically, a wall needs to be infinitely thick to stop all radiation, but 5m sounds decent, line that with lead, and voila.How much wall need to be thick to stop radiation and what material is used in that cases?
If it's reinforced with lead then yes

There are 3 types of radiation, alpha, beta and gamma

Nuclear bombs release game which will pass through nearly anything but can be stopped by thick lead

Beta can be stopped by thin aluminium

Alpha can be stopped by a thin piece of paper





Gamma is most likely to come from a nuclear explosion but beta an alpha may too depending on the design
