title: Australian per caput dose from diagnostic imaging and nuclear medicine.
abstract: The largest man-made contributor to the ionising radiation dose to the Australian population is from diagnostic imaging and nuclear medicine. The last estimation of this dose was made in 2004 (1.3 mSv), this paper describes a recent re-evaluation of this dose to reflect the changes in imaging trends and technology. The estimation was calculated by summing the dose from five modalities, computed tomography (CT), general radiography/fluoroscopy, interventional procedures, mammography and nuclear medicine. Estimates were made using Australian frequency data and dose data from a range of Australian and international sources of average effective dose values. The ionising radiation dose to the Australian population in 2010 from diagnostic imaging and nuclear medicine is estimated to be 1.7 mSv (1.11 mSv CT, 0.30 mSv general radiography/fluoroscopy, 0.17 mSv interventional procedures, 0.03 mSv mammography and 0.10 mSv nuclear medicine). This exceeds the estimate of 1.5 mSv per person from natural background and cosmic radiation.
