The natural radioactivity of Istria, Croatia [PDF]
Radiation Physics and Chemistry, 2019 Because of the geological structure of Istrian peninsula which mainly consists of a limestone that is characterized by karstic topography on its surface, it is expected that there are areas with elevated radon levels in soil gas as well as inside buildings (e.g. houses, kindergartens, schools).

Evidence for the Natural Radioactivity of Indium [PDF]
Nature, 1951 A CONSIDERATION of the energetics of radioactive decay shows that two isotopes of the same mass number but neighbouring atomic number cannot both be stable if the rest mass of the neutrino is zero. A number of such neighbouring isobaric pairs exists in Nature; in some cases the expected radioactivity has been found in one member of the pair, with a ...
