Short answer is yes. Backscatter is X-Ray and some in the medical field claim that any X-Ray energy represents risk, even though we all get X-Rays at the doctors’ and the dentist. This just adds to that mix.
L3 system operates in a different band on the spectrum and I haven’t heard any of the smart guys say that they had any safety concerns. I am not an expert, but the experts that I have talked to haven’t expressed concerns.
I travel frequently and have metal knees. I avoid the magnetometer whenever I can and pick the L3 whenever I can. I do go through the Rapidscan when I have to. (KC only has Rapidscan, so I use that outbound. Most return trips I can use a L3 machine.
The Rapidscan machine is the flat panel that you turn and face. The L3 machine is the one where you stand in a cylinder and the scanner revolves around you.
Thanks.
I'd go with a hand held scan if it was safe, and not look askance at carry on being scanned.
But, what about photo film and laptops? Can they go through any scan without crumbling?
What if they go into baggage; are film and laptops scanned?
