University of Bristol team use AARM in Arizona, USA
The University of Bristol Hot Robotics team have just completed a joint field mission with the University of Nevada, funded by the STFC's NuSec network, to radiologically map several legacy mining sites in the Copper Hills Mining District of Arizona to determine their residual radiation levels and contamination footprint. The AARM performed extremely well in desert heat and mountain snow!
The resulting maps clearly delineate the residual radiological footprint across the surface of the site, derived from tailings containing uranium-copper minerals such as Torbernite - Cu(UO2)2(PO4)2.8-12H2O
Further data processing work will now continue to extract NORM dose rates as well as advanced localisations of strong emitters.
Well done to the Bristol team!

Imitec demos AARM at the IAEA's first UAV workshop
At the end of September 2022, at an airfield near Brno in the Czech Republic, Imitec was given the opportunity to showcase its AARM technology in front of representatives from 62 UN countries at the IAEA's first workshop and demonstration of UAV-based radiation mapping.
The Imitec team was led by Professor Tom Scott, who also acted as a Workshop Technical Chair, with partners from Kromek and Drs Tomas Lazna and Petr Garlic from drone team from the Central European Institute of Technology (CEITEC).
At an airfield with hidden radiation sources the AARM was rapidly deployed, with the minimum of fuss, to rapidly identify two isotopically distinct radiation sources. Identification of location and isotope was achieved in real-time, proving that AARM really does lead the competition for speed, real-time visualisation, accuracy and ease of use.
