TSA to retest all body scanners for radiation levels

US Transportation Security Administration announced plans to retest every full-body X-ray scanner that emits ionizing radiation after maintenance records on some of the devices showed radiation level 10 times higher than expected (USA Today/Reuters, 13-Mar-2011). The TSA reportedly claims the figures are due to a mathematical error. There are 247 machines at 38 airports across the US to be tested. The TSA reportedly plans to publish the results.
