Description
Summary: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. •Advantages of TL dosimeters in diagnostic radiology are presented.•Personal dosimetry showed over exposition in interventional procedures.•Dose distribution in whole body by CT measurements are analyzed.•Personal dosimetry in diagnostic veterinary procedures need care with X-ray dose.•Integral dosimetry (INDOS) has been suggested as routinary dosimetric method in diagnostic radiology.
