While the federal Department of Education succeeds in its public relations push to place schools higher on the national news agenda, the Department of Homeland Security is making smaller strides over its rollout of full body scanners at airport terminals. The Transportation Security Administration managed to persuade CBS to make the new scanner at Boston's Logan Airport its lead story two weeks ago by granting an Exclusive to Bob Orr. Now NBC's Tom Costello gets access to cover the safety angle. Because the machine's X-rays bounce off the skin, he told us, the radiation dose is 100,000 times smaller than a CT scan of one's internal organs. Costello quoted the odds of contracting cancer from a scan at 1-in-100m, yet the number of scans will be "potentially hundreds of millions of travelers each year." So that means they will cause a handful of tumors annually.
