Measurement display: dose rate is displayed every second, and the protection alarm response is less than 5 seconds. 9. Operating environment: temperature -10C~+45C, relative humidity: 95% (+45C) Overview: The ionizing radiation detector has a built-in high-sensitivity cover technology tube as a detector. It is mainly used to monitor X, Y and hard -ray radiation in various radioactive workplaces. It has the characteristics of fast response and wide measurement range. Can display the current dose rate and cumulative dose rate in the workplace. Widely used in nuclear power plants, accelerators, steel, chemical industry, isotope applications, industrial X-y, radiation medicine, cobalt source therapy, gamma radiation, iodine 131, radioactive laboratories, monitoring of the surrounding environment of nuclear facilities and other fields for personal safety protection monitoring and radiation warnings.
