The instrument for detecting nuclear contamination is called a nuclear radiation detector.
Nuclear radiation detector is a kind of special instrument used to find and measure the nuclear radiation in the early stage of nuclear explosion and the remaining nuclear radiation. Nuclear radiation detector is usually by the detection gas, measurement components, display components and power supply components, used for wartime nuclear radiation detection, gas assessment of the human body suffered radiation damage or potential acute radiation damage in order to take protective measures.
In practical application, according to the instrument gas function and need to be selected. For example, γ-ray indicator can be used to find the radioactive smoke cloud to reach or contaminated border; dosimeter can be carried around, used to measure the personnel affected by γ radiation and neutron radiation absorbed dose. Nuclear radiation detector is with the introduction of nuclear weapons and appeared, after decades of nearly 2,000 different types of nuclear tests, instrumentation varieties and functions have been developed, and the formation of modern equipment series.
Nuclear radiation detector working principle:
х-γ radiation meter using highly sensitive scintillation crystals as a detector, fast response time, for monitoring a variety of radioactive workplace x, γ rays, radiation dose rate of the special instrument. Compared with similar instruments in China, this instrument has a wider range of dose rate measurement, and can accurately measure high-energy and low-energy x,γ rays, with good energy response characteristics.
Safety organizations, such as police and fire departments, emergency response organizations, environmental protection organizations, hazardous materials disposal, metal recycling companies, mines, etc., they are exposed to a variety of radioactivity of a higher chance. Ports, terminals, airports, etc., these places because of the large flow of people and all kinds of import and export goods, especially involving the entry and exit of people with a higher chance of radioactive contamination.
