Abstract In 2002 and 2003, the National Institute for Occupational Safety and Health (NIOSH) received health hazard evaluation (HHE) requests from Transportation Security Administration (TSA) employees at several airports, expressing concerns about a variety of issues including exposure to X-rays from carry-on baggage and checked baggage screening machines. TSA management also submitted a separate request for NIOSH to perform an independent study to determine the levels of radiation emissions from the various TSA screening equipment, and whether routine use of dosimetry is warranted. In May 2003, 12 airports were randomly selected for study. Basic characterizations of work practices, spot measurements for radiation, and employee interviews were completed between 2003 and 2004. Monthly radiation measurements were obtained from personal dosimeters issued to TSA baggage screeners. It was observed that Explosive Detection System (EDS) machines at several airports exhibited a flaw that could be a source of unnecessary radiation exposure to baggage screeners operating these machines. However none of the participants' doses exceeded the Occupational Safety and Health Administration (OSHA) permissible exposure limit. Furthermore, no doses exceeded 25% of the OSHA quarterly limit which would require employee monitoring. Recommendations include taking some defective machines offline and extending the evaluation to a larger number of airports.
