1、 Overview:
800B intelligent х-γ The radiometer is a shielding and leakage measurement and monitoring device used for diagnosing X-ray equipment. Simultaneously monitoring various radioactive workplaces x γ Handheld/portable environmental level x for radiation γ Radiation detection instrument, which uses highly sensitive scintillation crystals as detectors and has a fast reaction speed. Compared with similar instruments, the 800B model is intelligent х-γ The radiometer has a wider range of dose rate measurement and can accurately measure high-energy and low-energy x γ X-rays have good energy response characteristics. 800B intelligent х-γ Radiometers are widely used in medical, disease control, environmental protection, metallurgy, petroleum, chemical, radiation laboratories, commercial inspection, industrial testing, radiation processing, mines and other occasions that require radiation environment and radiation protection testing.
