Wide range gamma neutron integrated detection device

The wide range gamma neutron integrated detection device is a type of gamma neutron integrated radiation detection equipment, especially a wide range radiation detection device that integrates gamma and neutron.

The wide range gamma neutron integrated detection device consists of two wide range silicon semiconductor gamma detectors, two large-area sodium iodide scintillation detectors, and a He-3 proportional counter with a moderator（neutron detector）A total of 5 detectors form an integrated radiation detection device, mainly used for monitoring the neutron gamma mixed field radiation level generated by nuclear power plants in water drift reactors and other complex environments such as high salt, high humidity, high and low pressure.

2. Instrument functions

(1) Measurement of radiation: Simultaneously monitor gamma rays, neutron dose rate, and cumulative dose.

(2) Over threshold alarm function: The instrument can set high alarm threshold and low alarm; The alarm threshold can be set arbitrarily within the range; When the low alarm threshold is exceeded, the yellow warning light will light up; When the high alarm threshold is exceeded, the red alarm light will turn on and the buzzer will intermittently sound; When the dose is below the alarm threshold, the alarm stops.

(3) Can detect probe faults (failures) and sound an alarm.

(4) Wall mounted main control box: easy to install.

(5) Intelligent design: microcomputer control, dot matrix LCD display, Chinese status bar prompts for operation and status.

(6) Multiple probes can be connected externally, and here it is designed to connect three probes

(7) Standard RS485 interface: capable of transmitting collected data to remote control systems.

(8) Calendar clock function.

(9) Working power supply: AC220V AC power supply.
