Individual dose equivalent measuring system in complex environment

Abstract

The invention discloses a complex environment individual dose equivalent measuring system, which comprises a radiation monitor, a data reading device and a data management system, and is characterized in that the data reading device is connected with the radiation monitor and is used for acquiring dose data of the radiation monitor and uploading the dose data to the data management system; the radiation monitor comprises a gamma radiation monitor and an n-gamma radiation monitor; the data management system is used for providing user registration, equipment management, dose analysis, energy spectrum presentation and alarm recording, the system further comprises a network transmission module, the radiation monitor is connected with the data management system through the network transmission module, and the network transmission module adopts 4G / 5G and Beidou for transmission. According to the invention, comprehensive safety monitoring can be carried out on multiple aspects of radiation quantity, radionuclide type, real-time dose, dose equivalent rate and the like of individual irradiation; and when the exposure amount exceeds a threshold value, an alarm prompt is given.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation detection, in particular to a personal dose equivalent measurement system in complex environments. Background technique [0002] With the continuous development of nuclear technology, a large number of nuclear facilities with neutron radiation have been put into use, such as nuclear reactors, nuclear power plants, hash neutron sources, reprocessing plants, and military nuclear power plants. Ionizing radiation particles such as alpha particles, beta particles, neutrons and gamma are released, forming a complex nuclear radiation environment. Since the construction of the world's first reactors, nuclear accidents have occurred around the world, resulting in the continuous production of (inducing) ionizing radiation particles from leaked radionuclides, causing serious damage to those exposed to the surrounding environment. Irreversible radiation damage. Therefore, during the operation of n...

Problems solved by technology

[0009] Count-based dose measurement methods, even after energy compensation, still have large errors

At the same time, the existing n and gamma radiation monitoring equipment on the market usually use two detectors to respond to neutrons and gamma rays respectively, which cannot effectively avoid the influence of gamma background on neutron detection

The existing gamma personal dosimeter is a counting dosimeter, which can only provide an alarm function and cannot accurately measure the personal dose rate
