RAM-01 is a portable, multifunctional instrument for detecting radioactive surface contamination and measuring radiation dose rates. It is designed specifically for safety supervision departments, disease control centers, nuclear medicine, molecular biology laboratories, nuclear material transportation, and other aspects of surface contamination and X, γ radiation, based on the requirements of nuclear rapid emergency response monitoring technology. It is a highly sensitive, intelligent, and portable instrument. It combines the functions of a surface contamination monitoring instrument and an X, gamma dose rate meter, and can be used to measure both surface contamination caused by alpha beta and X gamma radiation dose rate. The display for measuring α and β \ \ γ can be switched, and the measurement is operated by the handle buttons. The measurement unit is cps \ cpm \ Bq/cm2, which can be converted Mainly used in disease control centers, radioactive workplaces, laboratories, hospitals, isotope production plants, workbenches, and other places with alpha beta radioactive contamination and gamma radiation for radiation dose rate detection.
