Description
Technical Field

Background
A Thermoluminescent (TLD) detector is a device that measures nuclear radiation using the thermoluminescent principle. After the detector is subjected to ionizing radiation, electrons are excited and transition, and electrons and holes are captured by a trap to form a stable state (ionizing radiation energy is stored in the trap). When the illuminated thermoluminescent detector is heated, electrons and holes are released, the electrons and holes are recombined to emit light, and energy in the trap is released in the form of light, converted into an electric signal by a photomultiplier tube and output for display. The released energy is proportional to the received ionizing radiation dose, and can be converted into the irradiation dose received by the detector to be detected through the scale. The detector is widely applied to the fields of radiation protection, radiology, radiobiology, geology, archaeology, environmental protection and the like, and is particularly widely used in personal dose monitoring and radiation environment quality monitoring.
In radiation environment quality monitoring applications, the main workflow of the detector is: 1) Preparing a detector; 2) Transporting to an application site; 3) Continuous monitoring at a specific location for no more than 3 months, typically 3 months; 4) After the monitoring is finished, the detector is retracted and transported back to a laboratory; 5) And (5) reading the detector by using professional equipment, and calculating a monitoring result.
When the detector is transported, the influence of the surrounding environment on the detector during transportation is difficult to deduct, so that the monitoring result is inaccurate and the error is large. There are two main solutions available: firstly, a detector is additionally arranged in the back and forth transportation process and is used for measuring the following background, the following background is deducted after the reading of the detector, and the method is complex and difficult to operate; secondly, the following piece is arranged, the whole process of transportation, monitoring and the like is followed, the following piece is placed in an environment far away from ionizing radiation during the working period of the detector, such as a common office and the like, after the detector is retracted for measurement and reading, the reading of the following piece is subtracted, and the method is not suitable for the environment with low background or small radiation influence, and the error of the monitoring result is larger.
