MONA in the sky

Airborne search for radiation sources: equipped with a helicopter and MONA, RSC is mapping Lithuania's radiation background and looking for sources.

The Lithuanian radiation protection agency RSC is creating a map of the country's radiation background. To this end, an 8-liter MONA with GPS was mounted in a helicopter. The first segments have already been surveyed from just a few hundred feet above ground. The data compiled during the flights are evaluated using ENVINET's NMC, which pre-processes and exports the files to a commercial GIS application to create the area profiles. Mounting MONA in a helicopter achieves an effective area average, thereby avoiding artefacts from land-based surveys. This means that factors such as recently paved roads and individual granite buildings are practically negligible.

At the same time, RSC can look for artificial radiation sources. Even relatively weak sources in remote areas can be tracked and distinguished from the background using MONA's spectroscopic capabilities, its high detection efficiency and the nuclide analysis for 1-second spectra. RSC and Lithuania are thus setting new standards in the proliferation control of radioactive materials.
