Introduction

FD-3017A radon survey water detector is a new model meter, it uses static to collect the first generation progeny-RaA of radon decay as measurement objects, then can survey soil or radon concentration in water quantitively. It has many features: no detector pollution problems, no radon emanation effect, high sensitivity, simple operation, site result gained (generally 5min, 3min fastest to complete one point measurement, the efficiency improves near 10 times more than foreign products), which is the most advanced soil radon detector at home.

Applications
Besides mineral, water prospecting and radon concentration determination, FD-3017A radon survey prospector can be also used to soil radon detection and water source seeking in construction project, radon measurement of department like earthquake forecast, EP and scientific research teaching etc. You can read counting rate directly and converse to Bg/m3 value after demarcating by authorized computation branch.

Technical parameters
1. Limit exploration sensitivity: <0.1 Bq(1Bq/L=0.27*10-10ci/L=0.27em)
2. Air pump sealing functions: when the pump ram is at 70mm, gas leakage velocity is less than 20mm Hg/min.
3. Detector: Au-Si surface barrier semiconductor detector, diameter is 26mm, area is 531mm2
4. Detecting efficiency: η2π≥40% (239puα endogenous activity area diameter ≤φ26mm)
5. Background: ≤4 pulse/h
6. Counting capacity: 1~99999
7. Equipment display: pulse numbers, HV indicate mark, measurement indicates mark, low voltage or voltage shortage indicates mark, date and time.
8. HV and measurement timing: several shifts in 0, 0.5, 1, 2, 3, 4, 5, 6, 10, 15, 25, 30min. Among them, 0min is manual measurement, that is HV or measurement will last to manual.
9. Data storage: ≥300
10. Preset coefficient and electricity drop protection function
11. Print content: pulse numbers, Bq/m3, data and time
12. Equipment alarm: HV time and measurement time alarm
13. It can work under the condition of -100c~+400c (temperature) and +40 c (temperature), 95% (relative humidity), comparing to normal condition, the counting error is ≤±10%
