Description

technical field [0001] The invention relates to the field of nuclear safety, in particular to an intelligent radioactive source searcher and its working method. Background technique [0002] With the development of radiation technology, the application fields of radioactive sources are becoming more and more extensive, covering all aspects of industry, agriculture, and scientific research. Various types and intensities of radioactive sources have been applied to a large number of fields such as medical diagnosis, industrial flaw detection, liquid level material measurement, container detection, radiation breeding, food preservation, etc. With the increasing number of radioactive sources used in various industries, although the awareness concept of nuclear safety and the management rules and regulations for the use of radioactive sources have also developed greatly, various factors such as improper operation of staff or lack of corporate supervision still cause various proble...

Problems solved by technology

With the increasing number of radioactive sources used in various industries, although the awareness concept of nuclear safety and the management rules and regulations for the use of radioactive sources have also developed greatly, various factors such as improper operation of staff or lack of corporate supervision still cause various problems. Incidents of loss of radioactive sources continue to occur

[0003] Once a radioactive source is lost, it is often very difficult to find and recover it. Due to the many possible areas involved and the large search area, the traditional radioactive source search method uses personnel to carry portable dose rate monitoring instruments to conduct a blanket search for suspected areas. It is difficult to make progress in hours, days or even longer, and the lost radioactive sources are often highly active and dangerous. The longer the search time, the greater the radiation hazards. Therefore, when a radioactive source loss event occurs, Finding and recovering radioactive sources quickly and efficiently and reducing their exposure time are important ways to reduce the consequences of accidents
