Introduction to Intelligent Gamma Radiometer (Special for Rapid Detection of Building Materials):

Intelligent gamma radiometer (specialized for rapid detection of building materials)Quickly and non destructively detect the total gamma radiation of building materials such as stone and ceramic tiles on site, and determine the radioactive category of building materials such as stone and ceramic tiles. The intelligent gamma radiometer (specifically designed for rapid detection of building materials) is used for geological exploration, radioactive environmental assessment, environmental and health monitoring, construction supervision, and rapid evaluation of indoor environmental radioactivity. Compliant standards/regulations GB/T 4835.1-2012 "Radiation Protection Instruments - β, X, and γ Radiation Surrounding and/or Directed Dose Equivalent (Rate) Meters and/or Monitoring Instruments and Portable Workplace and Environmental Measurement Instruments and Monitoring Instruments".

Instrument features:

• High sensitivity, wide energy response range, low power consumption, and good stability
• Easy to operate, displaying the A, B, and C categories of the tested stone in Chinese, and can also be displayed
• Display count rate and absorbed dose rate.
