Nuclear leak detector and method thereof for detecting pollution sources

Abstract

The invention discloses a nuclear leak detector comprising a lens and a body. A light reflector, an encoding template, a vacuum chamber, an optical fiber cone, a second image sensor, a lens group, a first image sensor, a power supply module, an industrial control module, a data acquisition module and a display screen are arranged in the body successively. The lens group is located above the lightreflector. The first image sensor is located above the lens group. The vacuum chamber includes a metal housing disposed between the encoding template and the optical fiber cone, a titanium window disposed on a side of the metal housing and close to the encoding template, a fluorescent screen disposed on the other side of the metal housing and close to the optical fiber cone, and a photocathode anda micro-channel plate that are both disposed in the metal housing and distributed in the direction from the titanium window toward the fluorescent screen. The nuclear leak detector detects nuclear pollution sources efficiently by a new detection method and improves the accuracy of the location display of radioactive sources so as to meet actual nuclear pollution treatment requirements.

Description

technical field [0001] The invention relates to the technical field of nuclear pollution / nuclear leak processing, in particular to a nuclear leak detector and a method for detecting pollution sources. Background technique [0002] With the increase of human demand for energy, the reduction of natural resources such as coal, and the advancement of nuclear energy technology, nuclear power has gradually become a must for people. Nuclear leaks and pollution have gradually become dark clouds overhead, and the Chernobyl incident and the Fukushima nuclear power plant incident have always alerted everyone. [0003] The radioactive pollution of nuclear pollution and nuclear leakage lasts for a long time, and the impact on humans and wild animals is silent. What's more terrible is that the location of the pollution source is difficult to find. At present, the commonly used detection method is the Compton camera. The detection efficiency of Cs-137: 662keV and I-131: 364keV) is only 0....

[0003] The radioactive pollution of nuclear pollution and nuclear leakage lasts for a long time, and the impact on humans and wild animals is silent. What's more terrible is that the location of the pollution source is difficult to find. At present, the commonly used detection method is the Compton camera. The detection efficiency of Cs-137: 662keV and I-131: 364keV) is only 0.16-2.8cps / MBq, not only the detection efficiency is low, it is difficult to meet the needs of actual detection and high-precision determination of the position of radioactive sources, but also the price is expensive (about $667,000 )
