HAHAHAHA.....OMG....Could you imagine radiation suits being worn by the crew? LOL! Lets not get OTT here.
In 10 years of flying I would say I have flown through an electrical storm maybe three times!!! It cant be any worse then going for xrays. We crew get exposed to higher doses of radiation throughout our lifespan then "landwalkers" as a result of so many hours in the air. My airline monitors this and if asked can tell us what our annual exposure has been.
Personally Im not worried!
