As Japan brings radiation into daily headlines, a new report from biomedical researchers finds that full-body scanners emit 'extremely small' doses of radiation, posing very little health risk to fliers.

Airport full-body scanners pose little risk to human health, according to an analysis by medical experts published Monday.
But the report, published in the Archives of Internal Medicine, appears unlikely to end all debate over the controversial devices. For one thing, the report didn't rate the health risks as zero. Also, easing concern about radiation levels doesn't assuage another worry: that the detailed full-body scans are an invasion of traveler privacy.
"The radiation doses emitted by the scans are extremely small; the scans deliver an amount of radiation equivalent to 3 to 9 minutes of the radiation received through normal daily living," wrote Pratik Mehta of the University of California, Berkeley and Rebecca Smith-Bindman, a medical doctor at the University of California, San Francisco in the new report.
