The Praga Radiometrics extension enables
you to map and process airborne and ground gamma-ray spectrometry data acquired by modern spectrometers using NaI (Tl) detectors. The feature-rich, GUI oriented software was specifically developed to perform whole spectrum gamma-ray data processing. 

This extension includes:

256-Channel Radiometrics

256-Channel Radiometrics Processing provides the capability to visualize and process 256 channel spectrometer data collected from airborne surveys. It supports the three main phases in airborne spectrometer surveying: acquisition, processing and presentation.

256-Channel Radiometric Processing

256-Channel Radiometrics Processing enables geoscientists to process and visualize 256 channel spectrometer data.

There are three main phases in airborne spectrometer survey data handling are — acquisition, processing and presentation. This extension is designed specifically for processing raw data collected from airborne surveys.

In addition to radiometric processing capabilities, this extension provides 1D non-linear filters to locate and remove data that is recognized as noise.

Use 256-Channel Radiometrics Processing to:

  • Import full spectra (i.e. arrays) of radiometric data using an Import Wizard
  • Display full "spectra" as profiles in a column of the database
  • View individual windows of spectra in database columns
  • Window K, Ur, Th and Total Count values simultaneously and store in unique columns
  • Window individual K, Ur, Th and Total Count values individually and store in a column
  • Subset spectra using sample ranges (i.e. to evaluate sub-windows) within individual spectra
  • Process windowed data using the standard reduction capabilities in the RPS system
  • Apply 1D Non-Linear Filter to remove very short wavelength, but high amplitude features from data

Praga 4 Radiometrics

The use of whole-spectrum information is consistent with the latest developments in the theory and instrumentation of gamma-ray spectrometry. The full-spectrum technique within the Praga Radiometrics extension includes a complete system of spectrum background removal. Aircraft, cosmic and radon background components can be separately adjusted by the user with the control of experimental calibration constants.

Visual control over various spectrum operations is an important feature. Using the spectrum browser, data can be displayed and analyzed on a spectrum-by-spectrum basis, allowing the user to evaluate the applicability of special processing methods such as spectrum-fitting or principal component analysis. There is a choice of relative (count rate) or absolute (activity, exposure and dose rates) outputs for all window, spectrum-fitting and principal component/window techniques. Another key aspect is the integration of the gamma-ray processing application with a gridding profile/grid viewer capability, for challenging tasks such as radon removal and man-made nuclide detection where multiple processing cycles are usually necessary.

Praga Radiometrics includes these five components:

  • A spectrum browser with tools for peak identification.
  • Window-based (ROI) processing following IAEA standards.
  • Advanced full-spectrum processing using least-squares fitting techniques.
  • Principal component (NASVD or MNF) analysis and spectrum processing.
  • Advanced support for radon removal including extended spectral-ratio and full-spectrum techniques.

Pico-Radiation-Air-to-Ground-Algorithm (Praga) software was developed by the Pico Envirotec and Spectronica. It is licensed and distributed by Geosoft as an Oasis montaj third party extension.
