Remote real-time monitoring method and device for nuclear radiation source equipment

Abstract

The invention discloses a remote real-time monitoring method for nuclear radiation source equipment. The remote real-time monitoring method comprises the following steps: (1) setting a remote monitoring device and an airborne monitoring device; (2) arranging nuclear radiation detection modules which work alternately; (3) the single-chip microcomputer module controlling the nuclear radiation detection module and counting; (4) electrifying the device; (5) when the radiation quantity is in an emission value range, the first nuclear radiation detection module carrying out monitoring; (6) when theradiation quantity exceeds a low-intensity high-point threshold value, starting a second nuclear radiation detection module; (7) when the radiation quantity is in the low-energy range again, startingthe first nuclear radiation detection module; (8) if the radiant quantity exceeds the low-intensity high-point threshold value again, starting a second nuclear radiation detection module; (9) when theradiation quantity is in the low-energy range again, starting the first nuclear radiation detection module; (10) repeating the steps (4)-(9) to monitor the nuclear radiation source equipment; and thenuclear radiation source device can be judged according to the counting value of the single-chip microcomputer. The method can prevent the nuclear radiation source device from being damaged.

Description

technical field [0001] The invention relates to the field of radiation safety monitoring, in particular to a remote real-time monitoring method and device for nuclear radiation source equipment. Background technique [0002] With the rapid development of nuclear technology and information technology, the application market of nuclear radiation sources is becoming more and more extensive. Through applications in industry, agriculture, medicine, and research, radiation sources provide enormous benefits to humanity and society, and make important contributions to scientific and technological progress. At the same time, the poor management of radiation sources has caused serious harm to the environment and human health. At present, the traditional supervision methods of radiation sources are mainly locking, warning and human care, etc. However, loss and leakage accidents abound due to human factors, which pose a huge threat to society and public safety.

Problems solved by technology

For mobile nuclear radiation source flaw detection equipment, its nuclear radiation source is usually installed in a safety shielding box (lead or depleted uranium material), and the radiation intensity around the instrument is not high, but when the equipment (such as a gamma flaw detector) performs flaw detection operations , the radiation source will be exported out of the shielding box, and the radiation source is always exported from one direction, which will cause the surrounding radiation intensity to be particularly large, which will easily cause irreversible damage to the monitoring equipment installed in the short distance; if the sensitivity of the nuclear radiation detection module If the sensitivity is too low, it will affect the accuracy of the radiation source detection results; if the sensitivity is too high, the monitoring equipment will be easily destroyed by high-intensity radiation and become invalid
