I would like demonstrable proof that X-rays of the intensity used in checking your hand-held luggage in airports will cause malfunctions or degradation of electronic equipment. Chapter and verse please. Is it causing impurities to migrate across junction boundaries? If so what amount X-Ray will cause this to happen. Is it playing Hobb with semi-conductor field effect transistors? How? Messing with capacitors? How. Heck - maybe it's exposure to gamma while at high altitudes and not the x-rays that would cause equipment problems in long high-altitude aircraft flights.
