摘要：
In this paper, we present the availability of an active pixel sensor (APS) with four transistors (4T) as a video monitor and radiation detector. Analyzing radiation damage must be one of the first steps in recovering from nuclear accidents, and the radiation response characteristic is the basis for the use of 4T-APS to detect radiation. The goal of this work is to suggest the use of cameras with 4T-APS in widely distributed irradiation detectors. The total ionizing dose (TID) of radiation damage on 4T-APS provided a threshold. Radiation tolerance was improved with the help of a radiation shielding structure. The radiation response showed integration time dependence and pixel information dependence, and greater radiation response was observed from the pixels with lower grayscale values. Two methods are suggested based on different monitoring scenes. This study can help to greatly improve nuclear accident emergency response and the safety of nuclear facilities.
