Abstract
Measurements of scattered radiation were made on 2 fluoroscopic installations, one with an overcouch tube and one with an undercouch tube. The annual doses to staff involved in a fluoroscopic procedure undertaken on both types of unit were estimated using measured dose rates and weighting factors referred to in ICRP [International Commission on Radiological Protection] 26. Environmental monitoring at the protective barrier was performed for various room layouts to determine the effect of equipment and room design on the annual dose received by staff at the control panel. In all circumstances the annual dose to staff inside the control cubicle was negligible.
