Adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation.2. Adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation. 3. Configured LCD color screen, with multifunctional monitoring pages, real-time display of current dose rate real-time value, cumulative measured value, cumulative stored dose rate, maximum value, average value, starting date, cumulative time. 4. The detector is used to measure X, γ and β rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides.4.
