An area where workers must follow defined protection measures, such as access control, dosimetry, training and contamination checks on exit, because doses or contamination could otherwise exceed set levels. A supervised area is a looser zone kept under review without special rules. US plants call the equivalent the radiologically controlled area, entered through a single access point with dosimeters issued and exits monitored by portal and personnel monitors.
You're not badged for the controlled area yet, finish rad worker training and dosimetry first.
