- 1. These G-M/Ion Chamber detectors are used as Process Radiation Monitors, but are functionally similar to the Area Monitors and are contained in the same cabinets.
- 2. These beta scintillation detectors are process type RIAs, however they are used in an area monitoring situation.
- 3. Radwaste Facility Area Monitor. Because the Radwaste Facility is not used as originally designed, these monitors are not used in a personnel radiation protection capacity as originally intended. Therefore, only the number and location are provided for these RIAs.
- 4. Radwaste Facility Area Monitor. Area Monitors have been statused as inactive. Power has been removed and these area monitors are not in service.
