I was wondering why that would be a bad idea and how much radiation sterilization is used today. Apparently about 40-50% of medical single use products are sterilized beforehand using radiation.

See if you can find numbers for food irradiation. Depending on country o ly a small number of foods is permitted to get that treatment but they're usually the large volume ones like wheat or flour.
