Probably for OP this isn't enough: if the radiation was carrying encrypted information then it would look random without knowing the "key", whatever a "key" could be in the context of a physical system. But I think that talking about encryption here without a solid preparation in the filed of physics it is just trying to apply something we know to try to solve some problem we have no idea how to approach.
