, , r a , Nuclear radiation dose detection instrument, a general term for technical equipment that detects and measures early nuclear radiation and residual nuclear radiation in a nuclear explosion. Referred to as dose detection instrument. Used for the detection and alarm of nuclear radiation, gamma dose rate (irradiation rate) measurement, radioactive contamination inspection and nuclear radiation dose monitoring, etc. It provides a basis for commanders to understand the nuclear radiation situation, determine troop combat actions and take protective measures. Dosimeters are usually worn by personnel and are used to measure the dose of gamma rays and neutrons and determine the degree of radiation damage to teams and individuals.

, , r 2. Dose detection instruments usually consist of detectors, measuring components, display components and power supplies. It uses various effects produced by the detector to absorb nuclear radiation energy, and is processed by the measurement component to complete the measurement of information, which is then recorded and displayed by the display component. Commonly used detectors include air (or high-pressure gas) ionization chamber, halogen Geiger Miller counter tube, scintillation detector, semiconductor detector, vacuum chamber secondary electron detector, as well as fluorescent glass, thermoluminescence and film detectors, etc. . Measuring components usually include various amplifiers, discriminators, converters, counters, etc. Display components include electricity meters, light-emitting diodes, fluorescent and liquid crystal digital display devices, as well as audio and light displays, etc. The power supply generally uses dry batteries or storage batteries, and the required voltage is obtained through DC conversion.
