LB 147 Personal Hand and Food Contamination Monitor

Personal Hand and Food Contamination Monitor

Product introduction           

The LB147 can be used for simultaneous alpha and beta/gamma measurements, or individually. The unit of the measurement result can be displayed as Bq/cm2 or cps, and each probe has a scale factor for each nuclide and a crosstalk correction for each alpha nuclide. Each probe is continuously monitoring the surrounding environment, and a long-term stable background value is used for compensation of contamination measurement. The monitor also checks for fluctuations in the current background before measuring.
