Description

technical field [0001] The invention relates to the technical field of radiation monitoring, in particular to a detection system. Background technique [0002] Environmental nuclear radiation monitoring refers to the monitoring of the existing radiation level in the surrounding environment of nuclear facilities, the content of radionuclides in the environmental medium, as well as the environmental parameters and social conditions required to evaluate the public dose. At present, the lower detection limit of common environmental dosimeters in my country is generally 20nSv / h, and the lower limit of environmental background is about 10nSv / h. In environmental nuclear radiation monitoring, the calibration of environmental dose monitoring instruments determines the safety of workers. According to the Verification Regulations for Environmental Monitoring Instruments (JJG521-2006), the energy response range of environmental monitoring instruments is 50keV~1.5MeV, and the lower limi...

Problems solved by technology

However, the adjustment process of the existing detection system is complicated, and it is difficult to realize the three points and one line of the radioactive source, filter and instrument through simple operations, especially when the radioactive source is placed on a long guide rail with variable travel. Therefore, it will affect the detection effect and accuracy; at the same time, the existing detection system is not convenient for adjusting the position of the radioactive source and the instrument. When the radioactive source is replaced during use, or the position is changed due to vibration, collision and other reasons, it is necessary to Very complicated operation to reset the position
