Description

The DINEUTRON is a portable device for measuring neutron dose equivalent rates and integrated dose equivalents.

The unit is based on an innovative dual-sphere concept developed by the CEA (French Atomic Energy Commission); this concept confers an excellent performance for a very reduced weight: 3.5 kg only. The device comes in a self-contained case including two 3He detectors with different diameter moderating spheres, the charge amplifiers, the processing circuits and power supply. A keypad allows to easily select the type of measurement and measurement unit. An alphanumeric backlit LCD display shows the equivalent dose rate, the integrated equivalent dose, the selected unit, the statistical accuracy, the quality factor, and the time of exposure when applicable.

Particular care has been taken in its design to the ergonomy (handle and balancing) to ensure a great ease of use and comfortable handling.

The DINEUTRON is the favored device for neutron ambient measurements in the scope of health physics and particularly in nuclear power plants, reactors and reprocessing facilities.
