Application: It is suitable for geological prospecting, radiation protection, nuclear accident monitoring, radiation dose evaluation, earthquake prediction and teaching. It can be used to measure the activity of radioactive element "radium" in water, rock, soil and other samples. It can also be used to measure the concentration of radon in the atmosphere, indoor environment and mine tunnels. Functional features: 1. Spherical ZnS (Ag) scintillation chamber is adopted for high sensitivity 2. Dual-channel digital detector, with single, serial and parallel measurement modes 3. Electromechanical integration design, each measurement cycle can achieve 10 samples of continuous automatic measurement, greatly improve work efficiency 4. The software design integrates measurement control, data analysis, storage and other functions, and displays the counting rate in real time in the form of atlas 5. The measurement results are stored in the form of Excel, which is convenient to consult, print and can be directly used for report publishing 6. The communication of the whole machine adopts industrial bus structure design, with high data transmission rate, strong anti-interference ability, multiple error detection and processing mechanism, and strong reliability Technical indicators: 1. Sensitivity: ≥ 110 cpm/Bq 2. Background counting rate: ≤ 2.50cpm 3. Counting capacity: 1 ~ 232 pulses 4. Repeatability error: ≤ 2.7% (measured using 239Pu α standard surface source) 5. Stability (8 h): ≤ 2.7% (measured using 239Pu α standard surface source) 6. Working efficiency (8h) Serial measurement: about 90 samples Measured in parallel: about 180 samples. 7.Power consumption: ~ 220 V / 50 Hz; about 50 W 8. Using ambient temperature: (5 ~ 50) ℃, relative humidity: ≤ 95% (40 ℃) 9. Data interface: USB interface 10. Shape size and weight: L900 × W450 × H800 (mm); weight approximately 60Kg
