MR-3235Nuclide identification instrument (portable gamma spectrometer)Introduction:

The MR-3235 nuclide identification instrument is a high-end portable gamma spectrometer that integrates X-ray detection, automatic spectral analysis, and automatic nuclide identification functions. The instrument uses a high-sensitivity scintillation crystal detector and a low-noise photomultiplier tube, with high detection efficiency. The application of digital 2048 channel analyzer and 32-bit microprocessor has improved the performance of the instrument, reduced the interference of environmental changes on the instrument, and provided a more flexible and convenient user operation experience. This instrument can quickly and accurately distinguish the type and radiation intensity of radioactive nuclides, and has search, detection, and alarm functions. It can be widely used in environmental protection, customs, security checks, metallurgy, industrial and mining enterprises, and research institutes, providing an ideal detection method for environmental radiation monitoring, nuclear anti radiation security checks, radiation source cleaning, and other nuclear technology application fields.

Compliant with the standard: ANSI-N42.34-2006 "Performance Standard for Handheld Instruments for Radionuclide Detection and Identification".
