Bertin Nuclear - Model NI-03 -Neutron Irradiator
The Neutron Irradiator provides a stable and controlled neutron field for the calibration and verification of neutron dose and dose‑rate measuring instruments. Designed to accommodate up to three sealed neutron sources—with optional gamma sources—it is ideal for nuclear installations, radiation metrology laboratories, and facilities performing routine dosimetry calibration.The NI‑03 Neutron Irradiator functions as a reference neutron flux generator, making it a core component in laboratories responsible for calibrating neutron dosimeters, survey meters, and other neutron‑sensitive instruments. It is commonly used in calibration environments where reliable and traceable neutron fields are essential.
The system includes a motorized rotary carousel capable of holding up to three radionuclide sources. A vertical lifting mechanism positions the selected source at the correct exposure height with high stability. Surrounding the irradiation chamber is a shielding structure made from neutron‑absorbing and gamma‑attenuating materials such as polyethylene, neutron‑stop compounds, and lead, ensuring safe operation for laboratory staff.
With automated controls and robust safety systems, the NI‑03 offers consistent performance for both routine calibrations and specialized neutron metrology tasks.
- Supports up to three neutron sources, with the option to include gamma sources for mixed‑field testing
- Mechanical indicator clearly showing which source is in the irradiation position
- Fully automated irradiation cycle ensuring precise, repeatable, and safe operation
- Integrated safety interlocks to maintain compliance with radiation protection requirements
