Radioactivity in drinking water: regulations, monitoring results and radiation protection issues
Annali dell'Istituto Superiore di SanitàINTRODUCTION: Drinking waters usually contain several natural radionuclides: tritium, radon, radium, uranium isotopes, etc. Their concentrations vary widely since they depend on the nature of the aquifer, namely, the prevailing lithology and whether ...

Journal of Radiation Research and Applied Sciences, 2017 Studies on environmental radioactivity in tropical Africa are scarce. Therefore, a baseline study of natural (238U, 210Pb, 226Ra, 232Th, 228Ra, 228Th, 40K) and anthropogenic (137Cs) radionuclides was carried out on Tema Harbour (Greater Accra, Ghana ...

Archaeology in Oceania, EarlyView.ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Journal of Radiation Research and Applied Sciences, 2018 Geological materials usually contaminated with naturally occurring radioactive materials (NORM) have become a focus of great attention. The radioactivity concentrations of 226Ra, 232Th and 40K in some ornamental stones in Egypt, were measured using a ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Turning Carbon Into Cash? Cross‐Country Evidence on the Profitability of Emission Reductions
Business Strategy and the Environment, EarlyView.ABSTRACT Does corporate CO2 abatement pay? We assembled an international panel of listed firms (2019–2023), linking Scope 1–2 emissions to institutional (G7, CCPI) and search‐based attention measures. The dataset consists of an unbalanced panel of 1724 multinational firms, together with a sub‐sample of 922 firms operating in G7 economies. Firm and time
