Radioactive Detection, radioactive material monitoring and nuclear radiation measurement

Gamma rays or neutrons emitted by radioactive materials interact with the detector medium (e.g., plastic scintillator, NaI(Tl) crystal, or 3He gas) upon entering the detector. Their energy is converted into electrical pulse signals, which are recorded by the data acquisition and processing system.

For a simple alarm system, the system determines whether the inspected object contains excessive radioactive material based on changes in the number of pulses recorded per unit time (i.e., the count rate).

In a nuclide identification system, these electrical pulse signals are recorded by a multichannel analyzer to form an energy spectrum (referred to as a "spectrum"), with pulse amplitude on the horizontal axis and pulse count on the vertical axis. Since different types of radioactive nuclides emit radiation at distinct energy levels, advanced nuclide identification algorithms can analyze the spectrum to determine the type of radioactive nuclide triggering the alarm, thereby providing users with additional decision-making support.
