Nuclide recognition device in high-level radioactive environment

Abstract

The invention discloses a nuclide recognition device in a high-level radioactive environment. The device consists of a digitalized gamma energy spectrum acquisition system, a monitoring host, mobile equipment and a wireless network, wherein the digitalized gamma energy spectrum acquisition system and the mobile equipment are controlled by the monitoring host through the wireless network. The nuclide recognition device has the advantages that: in the high-level radioactive environment, full-automatic nuclide detection is realized; the potential health harm suffered by workers during manual detection in the high-level radioactive environment is avoided and the shortcoming of the manual detection is overcome; meanwhile, the problem that information acquisition is finite during conventional nuclide detection is solved.

Description

technical field [0001] The invention relates to an intelligent device capable of identifying nuclides in a high-radiation environment. Background technique [0002] In a high-radiation environment, carrying out nuclide identification is a very important task in nuclear decommissioning and nuclear emergency. Its biggest features are: First, radionuclides release γ-rays and can produce radiation to objects or organisms entering the radiation field It is very dangerous for personnel to enter the site for detection; second, the detection area is often a closed area or an isolated area, and wired detection is limited; third, gamma radiation detection has statistical characteristics. [0003] At present, the main methods of nuclide identification in a high-radiation environment include: 1. Personnel carry equipment into the radiation field to carry out on-site gamma radiation detection, which requires strict protection for personnel. The detection operation is cumbersome and poses...

Problems solved by technology

[0003] At present, the main methods of nuclide identification in a high-radiation environment include: 1. Personnel carry equipment into the radiation field to carry out on-site gamma radiation detection, which requires strict protection for personnel. The detection operation is cumbersome and poses a potential threat to the staff; 2. Use a probe with a telescopic arm for detection. This method is limited by the length of the telescopic arm; 3. Install a gamma radiation detection device at a key position, and construct wiring to transmit the detection information to the control center. This method generally only detects The dose rate can not obtain richer information, and this method requires a large amount of construction, and it is difficult to implement in a high-radiation environment.

[0004] At present, the deficiencies of nuclide identification in the high-radiation environment mainly focus on: 1. The degree of automation is not high, and the on-site measurement of the staff is not only dangerous, but also time-consuming and laborious; 2. The measurement information is single, which cannot meet the needs of analysis and decision-making; 3. Due to the limitations of measurement methods, it is almost impossible to carry out measurements in high-radiation environments
