No I'm not. What good would it be carrying a geiger counter into a store to measure the radiation (if any) in the food. How are you going to tell where the source of that radiation is coming from?? You can't tell where it's coming from just by registering a few clicks on a counter. Neither would you have the lab facilities to do that testing...and it only works on certain radioactive isotopes in any case. Neither are you going to be able to tell what isotope is present in the food. You would be wasting your time and causing undue panic in those around you.
You're going to find that much of your food is slightly radioactive in any case as things like fruit etc, are irradiated by cobalt 60 sources to both sterilise them and hasten the ripening process. The ground you walk on is slightly radioactive...you're surrounded by a mildly radioactive environment.
If your food was significantly affected by radiation, you wouldn't be eating it. What's more, the radioactivity would set off the fire alarms in the shops if there was any significant radioactivity present. Fire alarms have small radioactive sensors in them that detect those particles in ordinary smoke. A hot source would easily set them off.
