Compact area gamma dose-equivalent-rate monitor with integrated backlit display, two adjustable alarm levels, optical and audible indication, and Ethernet interface for direct RMS integration. Local data archive of at least 180 days. Suitable for indoor and outdoor deployment — vault corridors, hot-lab boundaries, theranostic wards, waste-storage areas and facility perimeters.
Key Features
- Measurement of gamma dose equivalent rate for area-monitoring applications

Applications
The workhorse area gamma monitor — vault corridor to facility perimeter
Cyclotron vault entry / corridor
Continuous area gamma monitoring at the vault-entry interlock and along the access corridor. The 180-day archive documents the field across a full quarterly cyclotron-operation cycle for AERB inspection.
Hot-lab boundary
Area gamma monitor at the hot-lab clean-room boundary confirms that contained activity is not spilling into the corridor. The two alarm thresholds gate operator response — first level signals a check, second level triggers the area-evacuation procedure.
Theranostic ward — Lu-177 / I-131
Patient rooms with high-activity therapy patients produce a localised dose-rate field. Monitors in the ward corridor track the room-to-corridor field and document compliance with public-area dose limits.
Waste-storage area
Decay-store and active-waste store benefit from continuous area monitoring; the area monitor catches an unexpected dose-rate rise (typically a mislabelled vial or a damaged shielding container) before it becomes a contamination incident.
Facility perimeter
Outdoor area monitors at the facility perimeter document the public-area dose-rate consistent with the AERB facility licence. The Ethernet interface lets multiple perimeter monitors feed into the RMS server without intervening field hubs.
AERB inspection narrative
The 180-day local archive plus the RMS-server long-term trend produces an inspection-ready dose-rate record without requiring any reactive data-collection during the inspection visit.
Why Area Gamma Monitor?
Earlier-generation area gamma monitors connected via RS-485 — requiring an Ethernet bridge to reach the RMS server. The new generation has Ethernet as a direct interface, so the monitor connects to the building network without an additional translation device that becomes another point of failure.
A 180-day local archive ensures that even if the central RMS server is offline for an extended maintenance window, the dose-rate record is preserved on the unit itself. AERB inspection can read the local archive directly if needed; the dose-rate record is not held hostage by network availability.
Small sites or new-installation phases may not have the central RMS server deployed yet. The unit functions as a standalone monitor with on-board display, alarm thresholds and local archive. As the site grows into a full RMS architecture, the same monitor connects in without replacement.

FAQ
Area gamma monitor — questions we hear from Indian cyclotron RSOs
Why cyclotron facilities need continuous area monitoring instead of periodic surveys, what the 180-day local archive protects, when to pick standalone vs RMS-integrated, and the alarm-chain configuration.
Q.Why does a cyclotron facility need continuous area gamma monitoring rather than periodic surveys?
A cyclotron produces high activity during beam-on and elevated activity around the synthesis and dispensing chain for hours afterwards. Ambient dose rate at critical points — vault door, corridor, dispensing room, waste storage — changes minute-to-minute across the production day. Periodic hand-held surveys miss the peaks that happen between surveys. AERB Regulatory Requirements for Medical Cyclotron Facility expect continuous area monitoring at those critical points with a documented archive; the AGM-03 is the fixed-position area monitor that produces that continuous record.
Q.What does the 180-day local archive solve at AERB inspection?
AERB inspection reads the historical dose-rate record at critical points across the inspection window (typically weeks to months). If the central RMS server is offline for a maintenance window, or if a network outage lost data, the reconstructive audit becomes painful. The AGM-03 stores its own 180-day local archive on the unit — even if the RMS is unreachable, the dose-rate history at that point is preserved and can be read directly from the AGM-03 for the inspection.
Q.Standalone or RMS-integrated — which configuration for which facility?
Standalone AGM-03 for small facilities or first-installation deployments where the central RMS is planned for a later phase. RMS-integrated AGM-03 for full-scale cyclotron radiopharmacies where multiple area monitors, neutron monitors, stack monitors and hand-foot monitors feed into one central RMS server for facility-wide dose-history visibility. The same physical AGM-03 supports both modes — configured at commissioning.
Q.What alarm behaviour does the AGM-03 support?
Configurable alarm thresholds on instantaneous dose rate and cumulative dose over a defined window. Local audible + visual alarm at the AGM-03 location; alarm signal routed to the RMS server for facility-level acknowledgement and to the RDU-02 radiation display units at strategic corridor locations. Alarm acknowledgement is logged in the audit trail for the AERB inspection dossier.
Q.How is the AGM-03 supplied and installed in India?
Distributed across India by Saxsons Group. Supply covers the monitor, site-survey configuration, RMS integration (standalone or networked), commissioning against the AERB Regulatory Requirements for Medical Cyclotron Facility framework and India commissioning support.
