Product Description, Technical Parameters and Configuration:

The CIT-3000F Radioactivity Detector for Building Materials (Low Background Multi-Channel Gamma Spectrometer) is a new generation of intelligent low-background multi-channel gamma spectrometer developed by Sichuan Xinxianda Measurement and Control Technology Co., Ltd. on the basis of the existing radioactivity detector for building materials. It complies with the national new standard JJG417-2006 "China's Metrological Verification Regulations" and GB6566-2010 "Limitation of Radioactivity in Building Materials." This instrument leads the domestic field in technologies such as multi-channel spectrometers, automatic spectrum stabilization, activity measurement models, data acquisition and processing, and method research. It is a new intelligent nuclear measurement instrument suitable for measuring the radioactivity specific activity of building materials, minerals, the environment, and radon in activated carbon.
