title: Guidance levels in the Nordic countries: a preliminary report for selected interventional procedures.
abstract: The Nordic radiation protection authorities have already published recommended guidance levels for patient doses for six conventional radiological examinations. Over the past two years a similar protocol has been in progress for three interventional procedures. Measurements have been performed in 22 different hospitals in the Nordic countries on patients in the weight range 40-100 kg. The selected procedures are percutaneous transluminal coronary angioplasty (PTCA), percutaneous transluminal angioplasty (PTA) and endoscopic retrograde cholangio- and pancreatio-graphy (ERCP). A total of 281 PTCA procedures, 304 PTA procedures and 147 ERCP procedures are included in the study. The results from this survey are presented as a first attempt to set guidance levels.
