AT1120M, AT1120MA Spectrometers
AT1120M, AT1120MA Spectrometers
- Quick search and detection of gamma radiation sources with radionuclide identification
- Measurement of gamma radiation ambient dose equivalent rate
- High sensitivity and quick accommodation to changes in radiation level
- Short measurement cycle (1/3 s) provided by the search algorithm, enables highly confident estimation of rapidly changing radiation field dynamics and highly precise localization of radioactive sources
- Continuously recorded scanning data with GPS georeferencing
- Voice messaging option for identification results is available
- Expert "GARM" software for further data processing and analysis
