DA-4096 Low background multi-channel gamma spectrometer

Low background multi-channel gamma spectrometer

Product introduction           

It is composed of low-background NaI probe, program-controlled integrated multi-channel analyzer, computer, lead chamber and other equipment, and is mainly used for radioactive spectrum nuclide identification and activity measurement of gamma emitters. The hardware and software configuration of the system meets the requirements of the national standard GB6566-2010 "Limited Standards for Radionuclide in Building Materials" and GB/T 14582-93 "Standard Measurement Method for Radon in Ambient Air". It can be widely used for qualitative and quantitative analysis of radionuclides contained in materials such as granite, marble, cement, cinder, food, sediments and geological samples, and to measure the types of nuclides and their radioactivity or specific activity values; The activated carbon box method can be used to analyze the content of radioactive radon indoors or in the environment.
