FAST AND WIDE DETECTION - The radiation dose alarm instrument uses a high sensitivity Geiger technology tube as a detector to monitor X, gamma and hard beta radiation in various radioactive workplaces. It provides quick response and a wide measurement range. POWER OFF MEMORY - The Geiger counter displays the current and cumulative dose rates in the workplace. The calendar, time and accumulated data are stored permanently when the battery is changed. WIDE APPLICATION - Nuclear radiation detector is widely used in nuclear power plants, accelerators, steel and chemical industries, isotope applications, industrial X gamma radiography, radioactive stone, radioactive medical treatment, cobalt source therapy, gamma radiation, I-131, personnel in the field of radioactive laboratories, environmental monitoring around nuclear facilities, and other settings to conduct safety monitoring and radioactive warning. MEASUREMENT DISPLAY - The radiation dose rate is displayed every second, and the protective alarm response is less than 5 seconds. Typical use scenarios - In a nuclear power plant or nuclear facility, use for continuous area monitoring, early warning of increasing radiation levels during maintenance, and to verify safe access for workers. - In medical isotope facilities and radiopharmaceutical operations, use to monitor staff exposure and ensure dose limits are not exceeded during handling, preparation, and administration of radioactive materials. - In environmental monitoring around nuclear facilities or during site surveys, use to track ambient radiation levels, support decommissioning activities, and provide accurate, timely data for safety decisions.
