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
