For the purpose of radiation safety, healthcare worker classification is divided into two categories – those who directly work with radiation and those who do not directly work with radiation but may be exposed to it. Occupational dose limits apply to workers who directly perform radiation work. Hospital employees who do not directly perform radiation work are treated like members of the general public in terms of restricting exposure.
Several types of radiation protection clothes are available to X-ray techs. The use of these garments protects radiologic technologists from exposure to scatter radiation. However, some imaging modalities are associated with a very low exposure to occupational radiation exposure. Radiologic technologists performing these examinations may not require special radiation protection clothes.
In the US, each state has several organizations and multiple regulations pertaining to radiation safety and a department dedicated to enforcing those regulations. There are many more throughout the world including international organizations. To attempt to list all of the radiation agencies, policies, and laws in the US would fill volumes much larger then this book. Although the web of regulations is tangled, they are an important part of administrative controls.
