KuitunHY-8225 low-background gamma spectrometer

The HY-8225 low-background gamma spectrometer uses a low-background lead chamber and a low-potassium NaI(Tl) detector to measure the radioactivity of samples. It utilizes a high-performance digital spectrometer for high-precision gamma spectroscopy measurements of the NaI(Tl) detector. Upper-computer spectroscopy measurement and analysis software enables data acquisition, storage, processing, and spectrum analysis, ultimately identifying radionuclides in the samples and measuring their specific activity. This instrument comprises a low-background lead chamber, a low-background NaI(Tl) gamma radiation detector, a high-performance desktop digital spectrometer, and gamma spectroscopy measurement and spectrum analysis software. It features domestically leading automatic spectrum stabilization technology, ensuring long-term continuous operational stability and measurement accuracy.
