These cherries are very common. Malformed cherries are usually pulled and separated from the picture perfect ones. They are called either "doubles",
which are the ones that look like two cherries in one or "spurs" which look like a second cherry shriveled up and died on the side.
Were the cherries on sale? Like I said, these cherries are usually pulled from the rest and they are still sold but at a discount and only to food
sellers who don't require the cherries to be picture perfect. It makes sense that you found so many in one bag that way. My guess is that the place
you buy these cherries at has simply lowered their fruit appearance standards, you have bought these cherries from a new spot or a rouge bag of
doubles got mixed in with the shipment and you got "lucky".
Now as far as radiation? Who knows, I sure don't but I can tell you that the cherries appearance happens in nature, is very common and that they are
routinely separated from good looking cherries so it makes sense that so many would be found in one bag and that many people are not use to seeing
them.
I have been wondering about radiation as well, as I am a cherry addict and always have been. They may or may not be exposed to radiation but their
appearance is not a by-product of radiation exposure, it is all to natural. I would go ahead and eat them, I like the doubles personally.
