There is radiation all over the place. It isn't uncommon for radioactive packages to be shipped on aircraft. It requires a special container, depending on the activity. Radiopharmaceuticals are formulated to be rapidly shipped to a medical facility and administered at a specific time when the activity has been calculated to deliver the right dosage for testing or therapeutics.
Try walking around all day everyday with a rad pager like I do (part of the job)and you'll be surprised.
LOL...I know exactly what you mean.
Yeah so finding some on the airplanes that isn’t normal, is something eh?
