title: Radiation alarm at an airport after radioiodine therapy.
abstract: BACKGROUND
  Screening for radioactive material at borders may become more widely introduced in order to prevent illegal transport. All the alarms at Vienna airport so far have been due to recent applications of radionuclides for medical reasons.
  
  
  METHODS
  We report a patient who unexpectedly experienced this problem after undergoing radioiodine therapy.
  
  
  RESULTS
  We propose to inform patients routinely about this issue and to provide them with a certificate containing details of the administered radionuclide.
  
  
  CONCLUSIONS
  This could reduce problems for authorities, patients and institutions. This problem may not have arisen if the authorities had informed the appropriate groups before starting the security procedure.
