A survey of radiation doses to adults from diagnostic radiology in Victoria.
This study examines doses to adult patients from diagnostic radiology. Measurements were made at 37 hospitals and private radiology centres in the state of Victoria. Skin entrance doses in air were measured for the exposure factors used by the radiographer for an average size patient for the following procedures: abdomen AP; pelvis AP; lumbar spine AP, lat, LSJ; and skull AP, lat. There was a large range of doses observed for each particular procedure. Factors contributing to the range of doses were identified. Guidance levels for adult radiography based on the third quartile values of the skin entrance dose have been adopted for use in Victoria.
