Sources of ionizing radiation are used in some laboratory areas, including X-ray analytical equipment and radionuclides e. In most cases, such equipment or materials will be required to be under the control of an individual who holds an appropriate Radiation Licence. The use of sources of ionizing radiation is regulated by the Radiation Protection Act and Regulations which is administered by the Office of Radiation Safety in the Ministry of Health. Minimum requirements for use of sources of ionizing radiation are stipulated in Codes of Safe Practice that can be found on the Office of Radiation Safety website.
The University of Otago Radiation Safety Plan Code of Practice describes the general requirements for areas that use sources of ionizing radiation. As part of these requirements, departments, laboratories or other facilities that use sources of ionizing radiation must also have a Local Radiation Safety Plan that describes the sources of radiation to be used in that specific facility and how these will be managed to ensure the safety of staff, students, patients and the public.

Radiation Exposure Protection
Skip Navigation Bar. Key Information:. Key Information: In a radiation emergency, the choice of appropriate personal protective equipment PPE depends on Response role and specific tasks Risk of contamination PPE can protect against 1 External contamination Internal contamination via inhalation, ingestion, absorption through open wounds Other physical hazards e. Lead aprons worn in diagnostic radiology do not provide sufficient shielding against these kinds of radiation. See Types of Ionizing Radiation and Shielding Required PPE should include a personal radiation dosimeter whenever there is concern about exposure to penetrating ionizing radiation. Direct-reading personal radiation dosimeters may be used to monitor radiation dose and can help workers stay within recommended Dose Limits for Emergency Workers. Other respiratory protective equipment e.
While everyone is exposed to natural background radiation , workers may also be exposed to ionizing radiation in workplaces with radiation sources. These radiation sources can pose a health risk to workers if not properly controlled. Occupational settings with ionizing radiation sources include:. This Ionizing Radiation Safety and Health Topics page provides a starting point for technical and regulatory information regarding the recognition, evaluation, and control of occupational health hazards associated with ionizing radiation. The radiation protection guidance discussed here should be implemented within a framework of existing OSHA standards, including, as applicable, those for ionizing radiation and personal protective equipment PPE. This webpage discusses such standards generally and collectively. For example, mentions of "OSHA's Ionizing Radiation standards" refer to standards that protect workers from ionizing radiation in general industry, construction, shipyard employment, marine terminals, and longshoring.

Medical imaging has led to improvements in the diagnosis and treatment of numerous medical conditions in children and adults. There are many types - or modalities - of medical imaging procedures, each of which uses different technologies and techniques. Computed tomography CT , fluoroscopy , and radiography "conventional X-ray" including mammography all use ionizing radiation to generate images of the body. CT, radiography, and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered by the internal structures, and the remaining X-ray pattern is transmitted to a detector e. These exams differ in their purpose:.

Radiation protection , also known as radiological protection , is defined by the International Atomic Energy Agency IAEA as "The protection of people from harmful effects of exposure to ionizing radiation , and the means for achieving this". Ionizing radiation is widely used in industry and medicine, and can present a significant health hazard by causing microscopic damage to living tissue. There are two main categories of ionizing radiation health effects.
This study was performed to determine the knowledge, attitude, and practice KAP of health care workers HCWs towards radiation protection. In this systematic review study, three international databases Web of Science, PubMed, Scopus were searched for related published articles in the English language from 1 January to 1 February Out of the 1, studies examined, 41 studies that were performed on 11, HCWs were included in the final stage.

Jump to navigation. Time directly influences the dose received: if you minimize the time spent near the source, the dose received is minimized. For example, if possible, interview a nuclear medicine patient before drug administration not after. The exposure rate from a radiation source drops off by the inverse of the distance squared. For example, if a problem arises during a fluoroscopy procedure, stand on the image intensifier side of the C-arm if possible, or, when not assisting, step away from the patient if feasible. Use shielding : The third exposure control is based on the proper radiation shields, automatic interlock devices, and in-place radiation monitoring instruments.

Понимаете, я не могу отойти от телефона, - уклончиво отозвался Ролдан. - Но если вы в центре, то это совсем недалеко от. - Извините, но для прогулок час слишком поздний. Тут рядом полицейский участок. Я занесу им, а вы, когда увидите мистера Густафсона, скажете ему, где его паспорт. - Подождите! - закричал Ролдан. - Не надо впутывать сюда полицию.
Это аварийное электропитание в шифровалке было устроено таким образом, чтобы системы охлаждения ТРАНСТЕКСТА имели приоритет перед всеми другими системами, в том числе освещением и электронными дверными замками.
- Да тут несколько тысяч долларов. - Я действую по инструкции, сэр. - Пилот повернулся и скрылся в кабине. Дверца за ним захлопнулась. Беккер спустился вниз, постоял, глядя на самолет, потом опустил глаза на пачку денег в руке.
Я сам позвоню этому… - Не беспокойтесь, - прошептала Сьюзан. - Танкадо мертв. Все замерли в изумлении. Возможные последствия полученного известия словно пулей пронзили Джаббу.
