Embodiments of the invention provide a gantry-based radiation detecting system and method, and relate to the field of radiation detection. The radiation detecting system comprises a radiation detecting unit group and an alarm unit, wherein the radiation detecting unit group comprises a plurality of radiation detecting units; the radiation detecting units are in one-to-one correspondence with the radiation detecting areas; the radiation detecting units are electrically connected to the alarm unit and mounted on a movable gantry arm for detecting the radioactivity of the corresponding radiationdetecting areas and transmitting the radiation detecting data of the radiation detecting areas to the alarm unit; the alarm unit is configured to receive the radiation detecting data sent by the radiation detecting units; and when the radiation dose rate of the radiation detection areas is greater than or equal to a first threshold, the alarm unit outputs sound and light alarm information, which is used to indicate that the radiation detecting areas are radioactive contaminated areas. The radiation detecting system achieves the function of flexible installation and giving a specific contaminated area of the target to be detected.
Description
technical field [0001] The invention relates to the field of radiation detection, in particular to a gantry-based radiation detection system and method. Background technique [0002] The existing technical solution is a radioactive pollution detection system for vehicles composed of two or four large-volume plastic scintillators with the same function and symmetrical structure, photomultiplier tubes, front-end circuits and electronic components. The detector can only give whether the target to be detected is radioactive or not. The existing technical solutions have the problems of fixed installation and the fact that the radiation detection of the target to be detected cannot give a specific location. [0003] Therefore, there is currently a need for a radiation detection system that can be installed flexibly and provides a specific contaminated area of the target to be detected to solve the above problems.
