Many doctors don't opt out of the scans. Dr. Drew Pinsky calls the amount of radiation "inconsequential." However, some researchers question whether the manufacturers' measurements are valid -- the exposure to radiation may actually be 10 times more than what the manufacturers claim.
And Dr. Otis Brawley, chief medical officer of the American Cancer Society, takes a pat-down instead of going through a scanner when he travels. Brawley's deputy, Dr. Len Lichtenfeld, has the same opinion.
According to CNN:
"Lichtenfeld says it doesn't necessarily give him great comfort that the TSA says the scans are safe. 'I can still remember getting my feet radiated as a child when I went to the shoe store and they had a machine which could see how my foot fit in the new shoes,' he says. 'We were told then that they were safe, and they were not.'"
