Eh, it’s likely not an issue. There’s radioactive material in water runoff and all kinds of places. A small amount is not noticeable. Even in the worst case, these aren’t an issue. If they can be near your body 24/7 without causing problems, them getting spread out into even smaller pieces can only be less significant than that.

People are too scared by radiation. It usually isn’t an issue and you’re constantly interacting with it. It’s only in very rare circumstances where you need to worry.
