Initial results indicated radiation levels ten times more than expected from TSA's body scanners in use at nearly 80 airports across the country. The agency says a "calculation error" is to blame and operation of the 500 plus scanners will continue.

The TSA blog says even so, the errors do not impact safety.

Accoring to a Wired report ,TSA spokesperson Sarah Horowitz says field technicians are required to test radiation levels ten times in a row, then divide by ten for an average which testers frequently failed to do.

The Lochmere swim team overcame an 80-point deficit after the morning 10-and-Under session and surged past runner-up Shepherd's Vineyard of Apex to win the fifth-annual South Wake Invitational Meet at the Lochmere Swim and Tennis Club in Cary on Sunday.

The S.W.I.M., hosted by the Marlins of Raleigh Swim Team year-round club, drew 10 teams and almost 500 swimmers who compete in Wake County's Tarheel Swimming Association summer league. (Top finishers and record-setters are below.)

The meet was one of four championship-style meets being conducted for TSA teams by area year-round competitive clubs and community clubs. Greater Raleigh Swim Meet also was held this past Saturday, hosted by the New Wave Swim Team at the Triangle Aquatic Center in Cary.

With more than 10,000 youth swimmers on 78 teams this summer, the Tarheel Swimming Association long ago outgrew any single season-ending championship meet.

These days, four meets give the recreational summer league's swimmers a chance to experience a multi-team, championship-meet atmosphere.

Although the four meets being held this weekend and next in Raleigh and Cary are conducted by Wake County club teams and not the Tarheel Swimming Association, TSA teams are the invited participants.

The summer season splashed into action Tuesday evening as the Tarheel Swimming Association (www.tsanc.org) began its six-week run.

The dual-meet competition among recreational teams from community pools through the Triangle has added three new teams for a total of 78, TSA president Bob Goudreau said this week.

The number of swimmers - ages 18 and younger - should surpass 10,000 for the first time after passing 9,700 last year, Goudreau said.

The Transportation Security Administration uses something called millimeter wave technology for its full-body scanners at a growing number of U.S. airports including RDU's Terminal 2 ("RDU's new scanners see down to the skin").

It's hard to know just how explicitly the scan records the details of your sex, your surgical scars, and the rest of your body. You can certainly tell the boys from the girls.

One TSA official told USA Today: "You can actually see the sweat on someone's back."
