Background
People are always exploring effective ways to apply radiation to the fields of production, life and medical health, and actively seeking technical measures for radiation protection and aiming to minimize the harm of radiation. Radiation dose monitoring is the basis and premise of radiation protection, and the united nations atomic radiation effects scientific committee regularly reviews sources of natural and artificial radiation in the environment that exposes a population to radiation, and the associated risks posed by these sources, and regularly reports its research results to the united nations congress.
At present, the known radiation dosimeters are various in types, the energy response range is generally 30 kilo-electron volts to 3 megaelectron volts, and different types of radiation dosimeters can be selected according to the difference of the measured radiation dose and different application environments. There are mainly four types of dosimeters, depending on the detector chosen, based on ionization chambers, sodium iodide crystals, geiger-miller counter tubes and thermoluminescent dose plates, respectively. The first three detectors convert the detected radiation into current for output, and the output current is processed and converted into corresponding radiation dose; the thermoluminescent dose sheet is a thermoluminescent material which, after being irradiated by ionizing radiation, generates electrons and holes, a part of which can be trapped by traps in a metastable state, the number of the ionization-excited electrons and holes trapped by defects increases with the increase of the radiation dose, and when the material is heated, the electrons return to a ground state with the release of energy, a part of which is released in the form of visible light or ultraviolet light (thermoluminescent), and the intensity of the thermoluminescent light is proportional to the accumulated radiation dose.
In addition, the occurred leakage accidents of nuclear power plants, industrial nuclear pollution accidents, etc. not only cause harm to human health, but also cause long-term nuclear pollution to the natural environment in which human lives. Therefore, monitoring the radiation level in the environment at all times is a crucial issue. In order to prevent unnecessary nuclear radiation from damaging human bodies and polluting the environment, an XY dosage rate patrol instrument for environment monitoring is urgently needed.
An effective solution to the problems in the related art has not been proposed yet.
