AT1120, AT1120A RADIATION MONITORS

2-3
2-1-1
– Search and detection of low activity radioactive materials and sources
– Identification of radionuclide composition (option)
– Measurement of gamma radiation ambient dose equivalent rate
 
  • High sensitivity and wide energy range
  • Search algorithm with short measurement cycle (1/3 s) enables highly confident estimation of rapidly changing dynamics of radiation field and highly precise localization of radioactive sources
  • Automatic calculation of weighted mean energy
  • Scanning data are continuously recorded with GPS referencing
  • “GARM” application software for further data processing and analysis in expert mode (option)
  • “ARMS” application software for automatic transfer of data to a remote server (option)
