A method for detecting nuclear radiation

Abstract

The invention provides a nuclear radiation detecting method capable of performing long-term accurate nuclear radiation monitoring and nuclear radiation dose rate estimation on a dynamic environment around a video recording device. The method includes a step of acquiring a video recorded by the video recording device with a CCD / CMOS as a sensor in an environment requiring nuclear radiation monitoring under a condition of no shading dynamic scene, a step of performing frame processing on the recorded video to obtain a series of frame images and obtaining a differential image of each frame imageand an adjacent frame image, a step of detecting a moving object region in the differential image according to the obtained differential image and removing the moving object region in the differentialimage, a step of detecting whether the frame image contains a radiation bright spot according to the differential image with the removal of the moving object region, and a step of obtaining the radiation dose rate of the nuclear radiation environment where the video recording device is located according to a ratio of a number of frame images containing radiation bright spots to a total number offrames of the recorded video and a condition of the removal of the area of the moving object. The method is applicable to nuclear radiation detecting operations.

Description

technical field [0001] The invention relates to the field of nuclear radiation detection, in particular to a nuclear radiation detection method. Background technique [0002] The field of nuclear radiation detection has gone through the process from counting, to detection of nuclear radiation energy spectrum, to the current image display. At present, the most widely used nuclear radiation detection method is usually based on gas, scintillator and semiconductor materials. And based on the above media, various types of gas nuclear radiation detectors, scintillator nuclear radiation detectors and semiconductor nuclear radiation detectors have been developed. However, the gas nuclear radiation detector has a long dead time and is not suitable for high counting rate occasions, and the scintillator nuclear radiation detector is expensive and difficult to popularize. Semiconductor imaging equipment such as CCD / CMOS has begun to play a role in the field of nuclear radiation. CCD / CM...
