Abstract

The invention discloses a shielding device for a digital inverse-Compton high-purity germanium spectrometer and a method for using the same. The γ background of the surrounding environment and the soft components of cosmic rays are shielded, and the background caused by the hard components of cosmic rays can be reduced by using anti-coincidence technology. When the γ rays emitted by the tested sample are incident on the shielding shell, the Compton effect occurs. The photons will generate a non-all-powerful peak signal, and the scattered photons will enter the anti-coincidence shielding box at the same time to generate signals, and transmit the data to the data transmitter to the processor. The processor will compare and set the data range. If it exceeds the range, the processor will control The buzzer sounds an alarm, indicating that the shielding room is faulty, and sends the specific value to the display screen, which is displayed in red fonts. The invention solves the problem that the shielding effect of the shielding room is poor for the hard components of cosmic rays with strong penetration.

Description

technical field [0001] The invention relates to the technical field of high-purity germanium spectrometers, in particular to a shielding device for a digital inverse-Compton high-purity germanium spectrometer and a method for using the same. Background technique [0002] The radionuclides released into the environment as a result of human activities (eg, the nuclear industry, nuclear power plants, applications of nuclear technology, and nuclear weapons testing, etc.) are known as artificial radioactive backgrounds. These radionuclides are mainly fission products, activation products and transuranic nuclides. Among them, the fallout from nuclear weapons test and the radionuclide from the nuclear fuel cycle are the main sources of artificial radioactive background. [0003] In the fields of nuclear environmental monitoring, radiobiology and nuclear medicine, the specific activity of the sample is less than 40Bq / kg in most cases. This value is of the same order of magnitude a...
