Details:  TC-8500 Nuclear Radiation Detector  Overview  Dosimeters use Geiger-Muller counters to measure radiation. when every ray  Passing through the tube and causing ionization, the tube produces detection  Current pulses, each pulse detected by the tube circuit and recorded as  counting. , the displayed value of this dosimeter is the count value in the mode you selected.   Due to the randomness of radioactivity, the count value detected by the dosimeter  It changes every minute. Taking readings within the average range is more accurate  The longer the time interval, the more accurate the average count.   Detector is used to measure αβγ and X-ray radiation, most suitable for measuring small  Changes in radiation levels and high sensitivity to the most commonly used nuclides.    Application:  Application: 1. Security organizations, such as stations and fire brigade, emergency response organizations, environmental protection organizations, hazardous materials disposal, metal recycling companies, mines, etc., have a higher chance of being exposed to various radioactivity.  2. Ports, wharves, airports, etc., because of the large of people and various import and export goods, especially involving entry and exit personnel, the probability of radiation pollution is high.  3. Hardware factories, ceramic factories, hospitals, research institutions, laboratories, drug administrations, universities, etc., they have a higher chance of being exposed to various low-intensity or leaking radiation.  4. Private individuals who are concerned about the quality of the living environment and personal safety, such as someone who wants to find the surrounding environmental pollution at home, food, water, etc. (various emergencies or terrorist attacks, etc.).    Feature:  Sensor type: energy compensation type tube  Detectable types: Hard beta rays (β) Gamma rays (γ) X-rays  Energy range: 20kev～3.0mev≤±30% (137Cs-)  Sensitivity: 80cpm/μSV/(Co-60)  Test accuracy 0.01μSV/h  Real-time range 0-99.99μSV/h  Accumulated mileage 0-99.99μSV/h  Real-time error≤10%  Average error≤3%  1000 sets of data records  5V/USB 3.7V lithium battery/2200mAh power supply  Charging time 2-3 hours  Temperature range -20-60℃  Temperature Resolution 0.1%  Humidity accuracy ±2℃  Humidity measurement range 0～100%  Humidity accuracy ±3%  Humidity Resolution 0.1%  Screen display: 3.2-inch color screen (320*240)    Package Includes:  1*Radiometer
