Α/β low level counter LB790/LB761
Berthold Japan Co., Ltd.
About This Product
The LB790 low-level counter can simultaneously distinguish and measure low-level radiation (α-rays, β-rays) emitted by radionuclides. 10 channels (sample) can be measured. The detection limit is approximately 12 mBq for α rays (Am-241) and approximately 22 mBq for β rays (Sr-90).
The LB761αβ low level counter is a 200 mm planchet single sample measurement system with very low background count rates and good detection limits.
■Summary
・Integrated detector and sample slide
・User-friendly PC software AMS (for measurement and data acquisition)
・Service friendly regarding maintenance and repairs
・Guard counter (anticoincidence) to suppress cosmic rays on the measurement counter
■Function
・LB790: Simultaneous measurement of α and β (maximum Ø60mm 10 sample slides for planchet measurement)
・LB761: α and β simultaneous measurement (maximum Ø200mm 1 sample slide for planchet measurement)
・Paired detector module (2 detectors per module)
・Extremely low background is guaranteed by covering the entire surface with a 10cm lead shield.
■PC software: AMS
・Multiple detector systems can be connected in parallel at the same time (up to 4 systems)
・Automatic background subtraction
・Automatic half-life correction
・Live display of detected radiation and cpm value
- Saved measurement values can be displayed and evaluated on the monitor at any time.
・Data analysis with comprehensive graphical commands
