Japan passengers, cargo screened for radiation, radiation found at DFW and O'hare. I guess radiation from the TSA is ok, from Japan is bad?

Wonder if the radiation sensors would be able to pick up radiation from the scanners.

Radiation detectors at Dallas-Fort Worth and Chicago O’Hare airports were triggered when passengers from flights that started in Tokyo passed through customs, the New York Post reported.
