Paper Published

We are delighted to announce publication of a new paper, which showcases our innovative use of drone-based radiometric surveys, and our specially developed data processing methodologies, to produce high resolution 2D and 3D radiometric maps.

To demonstrate our newly developed methodologies, we focussed on quarry surveys. We conducted high spatial resolution mapping of selected quarries in Co Donegal, Ireland producing drone-based lidar, digital images, and gamma dose rate data sets. From these we derived a number of outputs, which include orthorectified maps and 3D models of the quarries, and both 2D and 3D maps of gamma dose rate, uranium, thorium and potassium concentrations.

Our outputs were used to create "digital twins" of the quarries, to demonstrate compliance with Irish and EU radiation protection legislation, and to aid the quarry operators in their planning and decision making for improved resource management.

The full article "Utilization of radiometric data for mapping primary and secondary sources of gamma radiation and radon/thoron release potentials in Ireland" is published in the top ranking journal Frontiers in Public Health, and is available here.
