Please visit our e-courses and tests page. We offer a range of online courses for X-ray techs to complete registration requirements for ARRT ® and other registries. This is in addition to the naturally occurring background radiation that everyone is exposed to, which is to the order of 0.3 rem/year, as well as man-made radiation exposure such as medical X-rays, which is to the order of 0.05 rem/year. This dose is limited to 2 percent of the permitted annual occupational dose or up to 0.1 rem/year whole body dose of industrial ionizing radiation. This is also applicable to healthcare workers who are non-radiation workers. In addition to the occupational radiation exposure limit, the yearly dose limit applicable to the general public has been defined. Lastly, the total effective dose equivalent is radiation delivered to the entire body. The external dose delivered to the entire body is known as the deep-dose equivalent. On the other hand, the lens dose equivalent is described as the radiation delivered from an external source to the eye. It is calculated at 0.007 cm deep, averaged over a 10 cm2 area. The external dose delivered to an extremity or the whole body, obtained from a source of radiation, is referred to as the shallow-dose equivalent. It is important to understand certain terminologies in terms of occupational radiation exposure limit. For the skin and extremities, the annual limit is 50 rems or 0.5 Sv. ![]() Deep-dose equivalent (delivered to any organ besides the eye) 50 rems or 0.5 Svįor the eye, the annual limit is 15 rems or 0.15 Sv.Total effective dose equivalent 0.05 Sv (equivalent to 5 rems) or, This dose of radiation results in between 17 and 28 cancer deaths among the 19,000 radiologists at risk, or an excess cancer risk of between 0.53 and 0.87.With regard to radiographers not specializing in radioactive materials, the code defines the annual exposure limit as follows: Whichever is more of the following: The annual limit for radiation exposure in the United States is outlined in the Code of Federal Regulations and similar state regulations. For the most part, they comprise of recommendations from the International Commission on Radiological Protection (ICRP) and other similar groups. The regulations regarding occupational radiation exposure limit of workers vary in different parts of the world. Occupational Radiation Exposure Safety Limits Read on to refresh your knowledge on the key safety limits with regards to occupational radiation exposure. Remaining within these limits is essential for safety in the workplace. There are certain occupational radiation exposure limits for X-ray techs. Radiologic technologists and other healthcare workers are exposed to X-rays in the course of their work duties. ![]()
