Gamma Surveyor Vario
Spectrum & Assay and Dose Rate modes can be performed as point, borehole and continuous readings accompanied with GPS coordinates.
Scintillation Bismuth Germanate Oxide (BGO) detectors and Sodium Iodide NaI(Tl) detectors in stainless steel housing. See Overview.
2048 channels, 3 MeV linearized energy range.
Selectable from 10 s to 2 h according to required accuracy of results and to estimated concentration levels of K, U, Th.
Factory calibration is done on high-volume K, U, Th and background standards according to IAEA recommendation (International Atomic Energy Agency).
Firmware is upgradeable via internet.
Data Management and Export:
Each measured file identified with file number, time of measurement, instrument serial number and complete headline is stored in memory of Gamma Surveyor Vario. This information serves for reliable data management (storage and processing) after data download from instrument. ASCII lines with MS Excel compatible structure consist of columns with results, GPS coordinates and remarks. Enclosed PC software provides data export of chosen results for processing by e.g. Surfer or Geosoft SW with either latitude / longitude or UTM coordinates.
Gamma Surveyor Vario PC software for Windows based PCs provides data download, export of measured files and visualization of spectra. The system contains complete support for data transfer using USB port or USB flash disk.
Rechargeable exchangeable Li-Ion battery, immediately ready to use, provides 24 h working time from one charging with minimum capacity loss at low temperature.
