The Transportation Security Administration (TSA) claims that backscatter scans are safe. But how do medical professionals personally feel about it?

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.
