Workers exposed to radiation, such as radiographers, nuclear power plant workers, doctors using radiotherapy, those in laboratories using radionuclides, and HAZMAT teams are required to wear dosimeters so a record of occupational exposure can be made. Such devices are generally termed "legal dosimeters" if they have been approved for use in ...
A medical radiographic exposure is always initiated by a human operator but an AEC detector system may be used to terminate the exposure when a predetermined amount of radiation has been received. [1] The intention of AEC is to provide consistent x-ray image exposure, whether to film, a digital detector or a CT scanner.
Lead shielding refers to the use of lead as a form of radiation protection to shield people or objects from radiation so as to reduce the effective dose. Lead can effectively attenuate certain kinds of radiation because of its high density and high atomic number; principally, it is effective at stopping gamma rays and x-rays.
Radiation emitted by radioisotopes or radiation generators is utilized in therapy for cancer or benign lesions and also in interventional procedures using fluoroscopy. There has been a tremendous increase in the use of ionizing radiation in medicine during recent decades and health professionals and patients are concerned about the harmful ...
Radiation Exposure Monitoring (REM) is a framework developed by Integrating the Healthcare Enterprise (IHE), for utilizing existing technical standards, such as DICOM, to provide information about the dose delivered to patients in radiology procedures, in an interoperable format.
Contact filters placed between the patient and the image receptor, where the photons that pass through the patient are recorded to form an image, do not limit radiation dose to the patient. [ 1 ] X-ray filters are also used for X-ray diffraction , in determinations of the interatomic spaces of crystalline solids.
Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
The term radiographer can also refer to a therapeutic radiographer, also known as a radiation therapist. Radiographers are allied health professionals who work in both public healthcare and private healthcare and can be physically located in any setting where appropriate diagnostic equipment is located, most frequently in hospitals.
