Abstract

The invention provides a radiation dosimeter, wherein the measuring instrument includes a built-in processor, and is respectively connected with the built-in processor to a wireless communication device, a display module and a power supply; the nuclear radiation detection device includes a connected NaI crystal probe, a photoelectric A multiplier tube, an amplifying circuit and a digital pulse amplitude analyzer, the pulse amplitude analyzer is connected to the built-in processor, the measuring instrument of the present invention has high sensitivity and good energy response characteristics, and can be used in medical treatment, and completion, nuclear submarines, nuclear power plants, etc. In areas with high radiation dose, at the same time, the measuring instrument is small in size, and the digital display of dose rate status is more intuitive.

Description

technical field [0001] The invention relates to the field of nuclear radiation detection, in particular to a radiation dosimeter. Background technique [0002] People have been exploring effective ways to apply radiation to the fields of production, life, and medical care. At the same time, they are also actively seeking technical measures for radiation protection in an effort to minimize the hazards of radiation. Radiation dose monitoring is the basis and premise of radiation protection. The United Nations Scientific Committee on the Effects of Atomic Radiation regularly reviews the sources of natural and artificial radiation in the environment that expose people to radiation, as well as the related risks caused by these sources, and regularly reports its research results to the UN General Assembly . At present, there are various types of known radiation dosimeters, and the energy response range is generally from 30 keV to 3 MeV. Depending on the difference in the measured...
