An answer from a drunk ex-chemistry current biotechnology student private pilot person....:. .Would say: NO!! From what I remember (please others correct me if incorrect!!) regarding radiation you should only be worried about emitters of ionising radiation that hang around (e.g. radioactive dust : alpha, beta and gamma emitters!...NOT X-ray machines!!). Any interaction between the radiation and the 'receiver' is short lived, and the energy is usually given out in heat...possibly light or sound etc once it hits the 'receiver'. X rays will not 'hang around' at all!!! If I were a high altitude pilot I would be much more worried about ionising radiation from other sources!!. .Do not worry about it (IMHO). .As always take my answers with a pinch of salt as I am sure someone will be able to find a large error in my reply!. .Cheers. <img src="wink.gif" border="0">
