AREA MONITOR FOR PULSE RADIATION

img_9079_0
Control of pulse radiation during operation of linear electron accelerators or other pulse action installations.
 
The monitor consists of AT1123 dosimeters and components of АТ2327.
 
  • Logging of dose rate levels and threshold exceeding events
  • Software for displaying current radiation environment in controlled area on PC screen
  • Backup power source
  • Fault diagnostics
  • Dosimetric control of both pulse and continuous gamma radiation
  • Operation of AT1123 dosimeter in off-line mode as a portable instrument
