Demo Data

This page contains the data that is described in the scientific publication Optimizing gamma-ray spectrometers for UAV-borne surveys with geophysical applications published in the journal of environmental radioactivity: https://doi.org/10.1016/j.jenvrad.2021.106717

The article is an open-access article and, therefore, accessible without a license.
The table below contains the data used in this publication in a CSV format. The table below

This article compares the results of three different sizes of Medusa gamma-ray spectrometers mounted on a drone with each other and with a ground-borne measurement in an agricultural field. The latter is chosen because agricultural fields have a relatively low radionuclide concentration, and therefore, the methodologies used in the article will also work in environments where the soil contains higher radionuclide concentrations.

The article concludes that you can use a detector as small as the MS-350 for environmental mapping of radionuclide concentrations in a field if you optimize the data processing and map-making process by using Full Spectrum Analysis (FSA) and Kriging.
