AT140 Neutron Calibration Facility
AT140 Neutron Calibration Facility
Reproduction and transfer of neutron flux density, ambient dose equivalent rate and personal dose equivalent rate units of neutron radiation during calibration, verification and testing of neutron radiation monitors and dosimeters.
- Fast and slow neutrons field in collimated beam
- Fast neutron field in "open" geometry using shielding cone according to ISO 8529-2
- Drum magazine for sources in polyethylene and concrete protection at 1-meter depth
- Software control of source movement and moving platform positioning
- Alarm and interlock systems, area monitors
- Control by operator panel or personal computer with automatic calibration capability
