Footnotes
1The use of the word ‘reflecting’ rather than ‘representing’ is intended to indicate that the process is consultative rather than based on consensus.
2In some States, some forms of non-medical imaging are considered to provide a benefit to the exposed individual (see, for example, Annexes II, III and IV).
3Dose constraints play an important role for category 1 practices. Since the procedures make use of medical radiological equipment, it would not be appropriate to limit doses to the dose limit for members of the public. It is also noted that diagnostic reference levels apply to medical procedures. These are levels used in medical imaging to indicate whether, in routine conditions, the dose to the patient in a given radiological procedure is unusually high or low for that procedure [2]. The dose constraints established for category 1 practices may well be lower than the diagnostic reference levels for the same procedures used in human imaging for medical purposes. For example, the dose from a CT (computed tomography) scan of the abdomen performed to detect swallowed drugs is likely to be significantly lower than that for a medically indicated CT scan of the abdomen looking for anatomical detail.
Introduction
1This case study includes cost–benefit analysis. The values used in the case study were applicable at the time that the case study was carried out in 2004.
