UPDATE: Has TSA glossed over radiation dangers of screening? ProPublica investigation raises troubling questions

UPDATED: The independent journalism Web site ProPublica has produced a long and thorough story examining how the Transportation Security Administration has glossed over the dangers of radiation emitted by one of its primary airport screening devices.

UPDATE:  Here is a followup story: TSA Administrator John Pistole told Congress the agency would study the dangers of X-ray scanners again.
