    would beta radiation follow an inverse square law like gamma and why or why not?

    Yes I believe so because it is radiation produced from a random event within a source, and hence has equal probability of going in any direction. So yes it would

    No it doesn't as both alpha and beta particles can't travel far enough in air so the inverse square law only applies to gamma radiation

    It only does in a perfect vacuum, alpha and beta ionize in the air and slow down, which is why it has a small finite range. Gamma is an EM Wave with large range and very weakly ionizes. The only factor that really has an effect on its intensity is distance so it can follow inverse square

    Well surely the inverse square law applies to all three in a vacuum, and none of them in air? While yes, interactions with air molecules are going to be much more common with alpha and beta, gamma photons will still interact with air causing the count detected at a certain distance from the source to be less than expected? I know I'm being pedantic, but personally I'd say that the inverse square law assumes no medium (other than a vacuum) to begin with, and hence it applies to al three.
