Description

technical field

[0001] The invention belongs to the technical field of nuclear technology application, and in particular relates to a single-energy gamma device. Background technique

[0002] Gamma rays (or X-rays) are short-wavelength electromagnetic waves with particle characteristics and strong penetrating power. They can be used in industry for flaw detection or automatic control of assembly lines. Gamma rays are lethal to cells and are used in medical treatment. tumor. Using the detector to monitor the gamma ray intensity can ensure the safety of the device and the validity of the experimental data. Radiation devices usually contain gamma rays of various energies, which are distributed in the range of tens of keV to several MeV. For gamma rays below 1MeV, the sensitivity of the detector has a relatively obvious energy dependence, and the energy response curve needs to be calibrated before use. The commonly used method for obtaining the energy-response curve is to use...
