Description

technical field [0001] The invention relates to the technical field of nuclear radiation detection, in particular to a device and method for automatically measuring gamma energy spectrum dose. Background technique [0002] Gamma radiation has a strong penetrating ability, is an important source of external exposure to human beings, and is also one of the main research objects for people to carry out environmental and occupational health assessments. In the past, people mainly used the total gamma counting method and the total gamma dose measurement method to measure gamma radiation. Such methods did not screen the gamma energy spectrum, and the measurement results had large uncertainties, which could not meet the current gamma radiation monitoring and evaluation. work needs. [0003] With the rapid development of radiation detection technology, gamma energy spectrum measurement technology is becoming more and more mature, and gamma energy spectrum measurement has become one...

Problems solved by technology

However, the existing gamma energy spectrometer can only measure the activity of the gamma energy spectrum, and cannot directly measure the dose of the gamma energy spectrum

[0004] In addition, with the development of the nuclear power industry, the field of nuclear and radiation measurement is also developing rapidly. However, the on-site calibration and calibration methods for fixed gamma radiation monitoring systems inside and outside nuclear power plants have not been fully established, and only the gamma spectrum activity can be carried out. Calibration and calibration, the problem of on-site calibration and calibration of the gamma spectrum dose of the fixed gamma radiation monitoring system needs to be solved urgently
