Diagnostic radiology dosimetry: Status and trends

Since 1970s the expression of protection standards shifted from a dose -to a risk‐based approach, with dose limits established to yield risks to medical radiation workers. Worldwide interest in patient dose measurement was stimulated by the publication of Patient Dose Reduction in Diagnostic Radiology by the UK National Radiological Protection Board (NRPB). This has resulted in the development of new dosimetric measuring instruments, techniques and terminologies which present challenges to those working in the clinic al environment and those supporting them in calibration facilities. In this sense, thermoluminescent dosimetry (TLD) has been actively developed in the past last 3 decades thanks to their successful applications in diagnostic radiology. The present work analyzes current status and future trends of diagnostic radiology dosimetry using thermoluminescence phenomena.
