Application: The measurement of soil radon concentration and radon exhalation rate is mainly used to find radioactive anomalies and evaluate the environment of soil radon. Functional features: Radon measurement by cumulative method has the advantages of small impact by environmental conditions, small lead chamber, high sensitivity, special activated carbon capture device and working correction source, data storage and playback function, standard USB communication interface. Technical indicators: 1.Measurement scope: Measurement range of radon concentration: (100,300000) Bq/m3 Radon exhalation rate: (0.001c10.000) Bq/m2 s 2. Sensitivity: ≥ 1.5s-1 (Bq/L) -1; 3. Energy threshold: 50 Kev; 4. Nonlinearity: ≤ 10b; 5. Repeatability: ≤ 10g; 6. Long term stability: ≤ 5% (continuous working 8 hours); 7. Use environment Temperature: (0 ~ 50) ℃; Humidity: ≤ 90% (40 ℃) 8. Shape, size and weight: Dimensions and weight of lead chamber :(34 * 15 * 20)cm;25 kg Operating table size and weight :(50 * 31 * 22)cm;1.5 kg 9. Power source: both ac and dc
