Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of portable radiation, and particularly relates to a portable radiation detection system suitable for multi-scene integration. BACKGROUND

[0002] In many fields such as industrial detection, safety inspection and medical diagnosis, radiation detection technology is widely used because it can penetrate objects and obtain internal structure information. However, with the increasing diversification of detection scenes, traditional radiation detection systems gradually expose many problems. In terms of scene adaptation, the spatial size and material density under different scenes differ greatly, and traditional radiation detection equipment often cannot be flexibly adjusted according to these specific parameters, resulting in poor detection effect, and even the detection task may not be completed due to equipment mismatch. Safety and accuracy are also challenges faced by traditional systems. The safety indicators such as device leakage radiation, grounding resistance and insulation performance lack effective detection and calibration, which not only threatens the health of operating personnel, but also affects the reliability of detection results. At the same time, single pulse dose control is not accurate, which is difficult to meet the strict requirements of different scenes on radiation dose. In terms of imaging quality, traditional radiation detection is difficult to clearly distinguish different substances such as organic matter and metal, and cannot provide high-quality enhanced images, limiting the depth and accuracy of detection. Data transmission and radiation protection cannot be ignored. When detecting moving targets, the frame rate of traditional systems is unstable, and ghosting easily occurs, affecting real-time detection effect. Moreover, the daily cumulative dose control of operating personnel is poor, and there is a risk of radiation safety. In addition, there is a lack of effective means for traceability of detection data and equipment maintenance, which makes it difficult to ensure the credibility of detection reports and the long-term stable operation of equipment. Therefore, it is of great practical significance to develop a portable radiation detection system suitable for multi-scene integration to solve the above problems and improve the adaptability, safety, accuracy and traceability of detection.
