Controlled Area 01
Controlled Area 01 : A defined area in which specific protection measures and safety provisions are or could be required for controlling normal exposures or preventing the spread of contamination during normal working conditions, and preventing or limiting the extent of potential exposures. A controlled area is often within a supervised area, but need not be. The term radiation area is sometimes used to describe a similar concept, but controlled area is preferred in Agency publications. Operations Area: A geographical area that contains an authorized facility. It is enclosed by a physical barrier (the operations boundary) to prevent unauthorized access, by means of which the management of the authorized facility can exercise direct authority. This applies to larger facilities. Radiation Area: See: controlled area. Site Area: A geographical area that contains an authorized facility, activity or source, and within which the management of the authorized facility or activity may directly initiate emergency actions. This is typically the area within the security perimeter fence or other designated property marker. It may also be the controlled area around a radiography source or a cordoned off area established by first responders around a suspected hazard. This area is often identical to the operations area, except in situations (e.g. research reactors, irradiation installations) where the authorized facility is on a site where other activities are being carried out beyond the operations area, but where the management of the authorized facility can be given some degree of authority over the whole site area. The site boundary is the boundary of the site area. Supervised Area: A defined area not designated a controlled area but for which occupational exposure conditions are kept under review, even though no specific protection measures or safety provisions are normally needed.
