South Korean airports Thursday began testing full body scanners to screen passengers, despite complaints from the state human rights watchdog that they violate personal privacy.

Body scanners showing the naked figure of passengers are a violation of basic human rights and thus should not be placed in airports, said a human rights panel.

The upshot: You may not get lung cancer from the machines, but your risk of skin cancer — particularly basal-cell carcinoma — could be significantly higher. In children, the impact may likely be even worse.

If you are planning to fly, be aware of your rights at airport security checkpoints. The TSA has mandated that passengers can opt out of going through a whole body scanning machine in favor of a physical pat down. Unfortunately, opting for the pat down requires passengers to be assertive since TSA screeners do not tell travelers about their right to refuse a scan.

Results of a survey of 7,300 amputees showed that travelers with limb loss have been subjected to inconsistent, unfair, abusive and often embarrassing screenings by TSA employees.
