| Summary: | In Iceland guidance levels for patient radiation doses are expressed in terms of kerma area product (KAP) for complete examinations. Radiological departments' compliance with these guidance levels is based on the average value from kerma area product measurements on a sample of patients. Along with the measurements, supplementary data linked to the performance of the examination are recorded, and analysed for influence on the measurement results. Key parameters recorded are the number of film-screen radiographs, fluoroscopy KAP rate and time, applied tube potential and speed of film-screen system. By comparing the average values of these parameters with other radiological departments or with guidelines for radiographic procedures, the reasons for a deviation from the guidance level can be identified. |
