The SPT-350 handheld nuclide identification instrument is a high-end portable spectrometer that integrates X-ray detection, automatic spectral analysis, and automatic nuclide identification functions. The instrument uses a high-sensitivity sodium iodide (NaI) detector and a low-noise photomultiplier tube, with high detection efficiency. The application of digital multi-channel analyzers and 32-bit microprocessors has improved instrument performance, reduced interference from environmental changes, and provided a more flexible and convenient user experience. It can be widely used in environmental protection, customs, security inspection, metallurgy, industrial and mining enterprises, research institutes and other units, providing ideal detection methods for environmental radiation monitoring, nuclear anti-terrorism security inspection, radiation source cleaning and other nuclear technology application fields.
