The Obama administration plans to spend $300 million in its push to install 1,800 full-body scanners in U.S. airports by 2014. But the Government Accountability Office estimated on Wednesday that personnel costs over eight years would run about $2.4 billion, because three TSA officers are needed to run each machine.

A Government Accountability Office official told the House Homeland Security Committee that a new cost-benefit analysis should be conducted prior to widespread deployment of the scanners.
