Air radioactivity in Marambio Base: The peculiar character of Antarctic Peninsula Open
The Antarctic region is considered to be the least contaminated in the world due to its specific location and separation of this area as well as low activity of humans (Hashimoto et al., 1988). Additionally, in accordance with the provisio…
