Nuclear power radiation environment simulation system based on UWB technology

Abstract

The invention discloses a nuclear power radiation environment simulation system based on a UWB technology, and the system comprises: a server which can receive a given simulation dose rate inputted bya user; at least one simulation radioactive source which is internally provided with a first UWB module, wherein the server is in communication connection with the first UWB module through the Ethernet; and at least one simulated personal dosimeter which is internally provided with a second UWB module, a timing module and a display screen, wherein the second UWB module is in signal connection with the first UWB module, the second UWB module, the timing module and the display screen are electrically connected in sequence, the timing module is used for timing the residence time of the positionwhere the simulated personal dosimeter is located, the second UWB module is configured to obtain a distance measurement value between the simulated personal dosimeter and the simulated radioactive source, calculate a simulated dose rate of the position where the simulated personal dosimeter is located based on the distance measurement value and a given simulated dose rate, and calculate a simulated dose of the position where the simulated personal dosimeter is located based on the simulated dose rate and a time value of the timing module, and a display screen is used for outputting and displaying the simulated dose rate and the simulated dose.

Description

technical field [0001] The invention relates to the technical field of radiation source detection, in particular to a nuclear power radiation environment simulation system based on UWB technology. Background technique [0002] The working environment of nuclear power plants is relatively close to the nuclear radiation source, and the radiation intensity they receive is also relatively high. When the staff work in the surrounding environment of the radiation source, they will cause great harm to the human body and cannot stay for a long time. The instantaneous radiation intensity (i.e. dose rate) received by the worker from the radiation source is inversely proportional to the distance between the worker and the radiation source. The closer the worker is to the radiation source, the greater the dose rate and the faster the total radiation increase; the worker The farther the distance from the radiation source, the lower the dose rate and the slower the total radiation increas...

AI Technical Summary

Problems solved by technology

[0003] However, since the newly trained staff have no practical experience in operation, when some emergencies occur, for example, when a nuclear leak causes the radiation intensity of the radiation source to increase instantaneously, the instantaneous radiation intensity received by the staff becomes larger in a short time. The total amount of radiation it receives is also likely to exceed the preset value, which is not conducive to the safety of the staff

Due to the lack of practical experience in dealing with emergencies, the staff is prone to panic and cannot perform relevant operations in an orderly manner according to the theoretical knowledge guided in the training manual
