ADAMOS Series

ADAMOS is an automated segmented gamma scanning system, designed to characterise drums filled with radioactive waste. The system layout can be defined from the available options to meet specific requirements.

ADAMOS stations are composed of:

• Mechanical structure: rugged steel frame with roll-gang conveyors
• Detection equipment: moving and collimated detectors, typically HPGe
• Management software: user-friendly operator interface

All versions of ADAMOS share the following features:

Scanning procedure

During the automatic scanning procedure, the drum is moved to a rotating platform in the measuring chamber, to be centred and weighted.

Then the detectors are vertically moved to intercept and scan the pre-set sub-sections of the total drum volume: a collimator set defines the detector field of view. The suitable measurement setup is automatically selected and applied by the software according the radioactivity level.

PLC and PC

All the actuations and safety devices of the system are locally managed by a PLC; an operator panel is available as user interface.

Safety devices

ADAMOS work cycle is managed by the system software, which sends commands to the PLC to start each macro operations, and constantly checks the system status to detect failures or anomalous conditions.

ADAMOS systems implement the “safety by design” principle to prevent any harm to operators and the system itself. ADAMOS stations are typically equipped with perimeter protections, emergency buttons and collision-proximity sensors.
