How about C)? You seems to be saying C) is safe? Option A has the most potential for damage. The CAT scanners are instant well done. Thats really all thats changed I think. The high dose X-Ray being used on checked baggage is relatively recent. The carry on X-Rays have always been problematic, I don't know if they have gotten worse or not. I am pretty sure the walk through is just detecting ferrous metals. If it was irradiating, it wouldn't be safe for people to pass through. William Robb
