Alpha-Beta radiation detector performs the following functions: measurement of α- β- radiation flux density, search for α- β- radiation sources.
BDAB can be used by radiological and isotope tracing laboratories and customs officers, first responders, police, emergency teams.
Operation Principle
A built-in detector based on the proportional counter is used to register a- and β- radiation flux density (DER, count rate). Data communication channel enables information exchange with Spectroscopic Radiation Monitor РM1403 / Display and Control Unit PM1403 by RS-485 interface.
BDAB enables the user to set and constantly monitor the threshold level of α- and β- radiation fluxes through the whole measurement range and record the set threshold level of α- and β- radiation density values in the instrument’s non-volatile memory.
Spectroscopic Radiation Monitor PM1403 Operating Mode
When the instrument is connected to the Spectroscopic Radiation Monitor РМ1403 / Display and Control Unit РМ1403 / Display and Control Unit РМ1403-01 or PC it enables:
- α- measurement of β- radiation flux density
- α- measurement of β- radiation flux density
- search for α- and β- radiation sources
- program operation modes
