In the area of optimization in diagnostic radiology there is considerable scope for reducing doses without loss of diagnostic information, but the extent to which the measures available are used varies widely In diagnostic radiology, this may involve transferring a technician from fluoroscopy to CT scanning or some other area where there is less scattered radiation to workers.

Introduction. With the advancement of medical imaging devices, diagnostic imaging techniques to detect different diseases are increasing rapidly. 1, 2 The goal of radiography is to produce appropriate diagnostic images to establish the appropriate diagnosis while simultaneously protecting patients against radiation. The increasing incidence of X-ray examinations raises concerns about the full. The radiation protection survey is intended to focus on radiation safety and checks for compliance with the appropriate requirements of . NRL C5. As part of this, the radiation protection survey acts as an external independent audit of the quality assurance programme. The tests and measurements made during a radiation One method of reducing radiation exposure in diagnostic radiology is by justifying the examination, avoiding repetitions, and maintaining complete medical records. Up-to-date clinical information and compilation of a past imaging record ensures that useless tests are not performed. The outcome of the proposed examination, whether positive or. Lead aprons are used in medical facilities to protect workers and patients from unnecessary x-ray radiation exposure from diagnostic radiology procedures.

General principles of radiation protection from the hazard of ionizing radiation are summarized as three key words; justification, optimization, and dose limit. Because medical exposure of radiation has unique considerations, diagnostic reference level is generally used as a reference value, instead of dose limits The aim of radiation protection in dentistry is to obtain the desired clinical information with minimum radiation exposure to patients, dental personnel, and the public. During an average radiological examination, the radiation dose received by an individual is generally low and relatively few cells are damaged TS7e: Radiation Protection Challenges in Interventional & Pediatric Radiology.

Population-based studies show that the use of diagnostic imaging has exploded over the past two decades, with one population-based study showing that the number of CT scans per 1000 adult patients nearly tripled between 1996 and 2010. This has led to a dramatic increase in ionizing radiation. Although radiation doses to a fetus tend to be lower than the dose to the mother, due to protection from the uterus . and surrounding tissues, the human embryo and fetus are sensitive to ionizing radiation at doses greater than 0.1 gray (Gy). Depending on the stage of fetal development, the health consequences of exposure at doses greater than.

Introduction. First introduced for diagnostic radiologic examinations in the 1990s (1 -3), reference levels are a quality assurance and quality improvement tool for controlling radiation dose.They are intended to be a reasonable indication of dose for average-size patients and to provide guidance on what is achievable with current good practice rather than optimum performance () In Switzerland, albeit responsible for only 6% of the studies that have used ionizing radiation in 2008, CT was accountable for 68% of the annual medical radiation exposure . An early focus on the potential health effects of radiation exposure from CT began in the early 2000s ( 5 , 6 ) During the last decades, radiation protection and dosimetry in medical X-ray imaging practice has been extensively studied. The purpose of this study was to measure secondary radiation in a conventional radiographic room, in terms of ambient dose rate equivalent H*(10) and its dependence on the radiographic exposure parameters such as X-ray tube voltage, tube current and distance The responsibility for clinical radiation safety and infection control lies with every individual involved with diagnostic and research radiology including faculty, students, clinical staff, and other individuals who are responsible for the proper use and maintenance of radiation equipment and supplies (including film, darkrooms, and processors) A basic diagnostic imaging quality assurance program is a regulatory requirement in many provinces Footnote 1, Footnote 2 Footnote 3 Footnote 4 Footnote 5 and in federal institutions.

Radiation dosimetry is the measurement, calculation and assessment of the absorbed doses and assigning those doses to individuals. It is the science and practice that attempts to quantitatively relate specific measures made in a radiation field to chemical and/or biological changes that the radiation would produce in a target The risk of adverse effects, including cancer, from diagnostic radiology procedures is small, but the use of medical radiation, especially CT, is steadily rising. Before referring a patient for a medical imaging test that uses ionising radiation, the GP should ensure that the procedure is justified, and that alternative tests not using ionising.
