Fixed integrated device for monitoring regional gamma neutron radiation

Abstract

The invention relates to a fixed integrated device for monitoring regional gamma neutron radiation. The device comprises a gamma detector, a neutron detector and a host system connected with the gammadetector and the neutron detector through an RS-485 communication network, wherein the host system is connected with a detection signal processing and display system, the gamma detector comprises a plurality of gamma probes, the neutron detector comprises a plurality of neutron probes, the detection signal processing and display system comprises a signal processor connected with the gamma probesand the neutron probes, and the signal processor converts detector signals of the gamma probes and the neutron probes into digital signals. The device is advantaged in that gamma and neutron dose monitoring and dose data management in complex radiation places such as a nuclear reactor are completed by using one dose monitoring system, a GM detector and a 3He proportional counter are selected as main detection instrument probes and are organically combined into a region gamma and neutron detection device, the monitor is beneficial to simplifying equipment complexity of a radiation monitoring system in a nuclear power facility place, and the arrangement space is saved.

Description

technical field [0001] The invention relates to the field of radiation protection, in particular to a fixed integrated device for regional gamma neutron radiation monitoring. Background technique [0002] With the rapid development of the use of nuclear technology, we are also required to speed up the pace in the field of radiation protection to ensure the safety of workers in radiation workplaces. Among them, gamma dose rate and neutron dose are one of the important monitoring contents, which can directly respond to workers The size of the dose received and the safe operation of the facility. Nowadays, on-site radiation dose monitoring is set up in nuclear facilities, among which gamma radiation dose is the most common detection item. For nuclear facilities with complex radiation environment, such as nuclear power plant reactors, research reactors and other nuclear power plant reactor containment and nuclear power plant control In radioactive control places such as radiati...

Problems solved by technology

However, the quality factors of neutrons and gamma rays are very different, and the absorbed dose measurement principle and detector design are also different, which brings interference to neutron dose measurement

[0003] Moreover, the current monitoring of the gamma and neutron mixed radiation field is mainly a portable detection instrument, there is no area monitor
