It is perfectly safe. Standard procedure today is to remove the laptop and place it separately ina bin. It goes through like that. X-Rays have no effect on magnetic media. The only risk is from EMI due to a malfunctioning machine - but in about 16 trips, that has never been a problem.
Digital cameras are also not a problem. The XRays have no effect in such media unlike film cameras.
The biggest problem I have is needing 3 or 4 hands to do everything.
1. Remove laptop and place in bin.
2. Remove shoes and place in a different bin along with jackets and pocket litter.
3. Remove belt buckle and put it in bin
4. Put camera case in bin, and - don't forget the laptop's case.
The real fun comes when trying to collect all of that and reassemble yourself to move on to your gate. Allow a good 10 minutes to get your act together.
