germanyBERTHOLD LB 124 B Surface Contamination Meter
Product introduction:
l pollution monitorThe LB124B filled xenon proportional counter technology is a versatile and flexible tool based on practical radiation protection.
l Can be used to encounter contamination caused by any radioactive material and have to be monitored
l LB 124 B has a high sensitivity to beta particles and gamma It is particularly suitable for measuring photons of radionuclides
l The measurement of radioactive contamination on surfaces with the beta-gamma contamination monitor LB 124 B is based on the proven xenon-filled proportional counter technology
l This detection technology provides the highest sensitivity
l Ideal for measuring photon radionuclides widely used in nuclear medicine, as well as in other laboratories and environments
l pollution monitorLB124B is a portable battery powered instrument with a sensitive area of 150 cm2
l It consists of a sealed xenon-filled proportional counter tube, a microprocessor board with display unit, and an amplifier and discriminator module for signal processing with a high-voltage power supply.
l For better detection protection with guides install an additional light grid or use a sample holder with drawer for small sample measurement activities
l The LB 124 B has an attractive and ergonomic design and due to its low weight it is easy to handle
l Even under adverse conditions, measurement results can be easily read on the large-screen high-resolution display with background illumination
Features:
l Light weight, easy to handle and sturdy instrument
l wide temperature range
l simultaneously independentZnS(Ag) α and β-γ contamination measurement detectors
l High sensitivity and uniform response
l No gas required for calculation
l Dose rate detection
l The front side of the detector instrument is positioned parallel to
l The energy response isH* (10) surrounding dose equivalent
l Halogen quenched Geiger - Miller tube
l Dynamic range:0.1 microsievert/hour to 20 millisievert/hour
l Energy range:50 keV to 1.3 MeV
l Alarm threshold dose rate measurement
l Select units: Microsievert/hour
l Dose accumulation is possible
