OverTheGeicoE writes "TSA recently announced that it is looking for vendors of 'radiation measurement devices'. According to the agency's Request for Information, these devices 'will assist the TSA in determining if the Transportation Security Officers (TSO) at selected federalized airports are exposed to ionizing radiation above minimum detectable levels, and whether any measured radiation doses approach or exceed the threshold where personnel dosimetry monitoring is required by DHS/TSA policy.' A TSA spokeman claims that their RFI 'did not reflect any heightened concern by the agency about radiation levels that might be excessive or pose a risk to either TSA screeners or members of the traveling public.' Concern outside the agency, however, has always been high. TSA has long been criticized for its apparent lack of understanding of radiological safety, even for its own employees. There has been speculation of a cancer cluster, possibly caused by poor safety practices in baggage screening."
