Abstract

Background
The National DRL (Diagnostic Reference Levels) values should be considered by employers when setting their local DRLs as required by the Ionising Radiation (Medical Exposure) Regulations 2017. As Digital Radiography (DR) does not give a visual indicator whether an image is underexposed or over exposed, it is important that dose to the patient is continually monitored. This study explores reasons for exceeding DRLs and discuses corrective measures taken.
Purpose of Poster
The learning outcomes will be applicable to staff using Computed Radiography and DR.
1. Evaluate the results of an audit of radiation dose levels.
2. Describe how to investigate examinations exceeding the DRL.
3. Recommend corrective measures to reduce doses below the DRL.
Summary of Content
The poster will include the results of an audit of 13 x-ray rooms in one hospital Trust. Data will discuss the range of patient weight, exposure factors given, dose received and detector dose indicator (DDI) relevant to each manufacturer for patients between 50kg to 90kg. Initial results demonstrated that two of the DR systems were consistently above the DRL. Interrogation of the images showed sub optimal radiographic practice and suggested little evidence of collimation of the radiation field. Training sessions were held for staff and sample images were used to discuss corresponding image quality, collimation and dose levels. A repeat radiation dose investigation was undertaken after a period of weeks. Results showed that all radiation doses were below the NDRL, resulting in the establishment of a new local DRL.
