γ Ray Surveying Instrument
γ ray surveying instrument is a kind of radioactivity surveying instrument controlled by microprocessor chips. γ ray surveying instruments can be used for:
1. Fast γ abnormality survey over a large area
2. Lithological logging of tunnels and trenches
3. Semi-quantitative analysis of uranium mine samples in field
4. Radioactivity survey of environment and residential construction and decorations
5. Search for underground water and examination of building foundation
