Five Radiation Sources Dataset Based on Pulse Energy Sequences

The core hardware of the system uses a 1.5-inch LaBr_3 detector, paired with a digital multi-channel analyzer that supports List mode. In the experiment, the conversion and derivation of various radioactive source activities were completed by combining the half-life of the radioactive source, the time interval between the production date and the actual measurement date.

Each dataset of radioactive sources contains pulse sequences collected at different detection distances (with a distance error of less than 0.5cm), which are used to comprehensively verify the actual detection performance of the nuclide identification algorithm. All pulse energy data have been calibrated with energy scales.
