I had a plane last week from Warsaw Modlin to Barcelona and I had one untypical procedure. It's my 14th flight and I never had something similar before. At the security scan right away after I crossed through metal detector the security guy came to me and scanned both my hands from both sides by some strange scanner. My hand were clear and I haven't anything on them, so I didn't get what he was searching for... Did he search for powder/radiation or something other? He didn't scan everyone there, but just a couple of persons.
So what he was searching for with that scanner?
