Radioactivity of Egyptian oil ashes
The activity concentrations of the Egyptian Heavy fuel oil (HFO) ashes are mainly caused by 210Pb and 226Ra (Fig. 1). The radioactivity due to 238U and 232Th was found to be negligible (2-21 Bqkg-1). The average activities
Stellar dinosaurs in the prehistory of the Solar System
Prehistoric dinosaurs and the time when they were roaming the Earth have been discovered thanks to the bones we find and their radioactive content. In the same way, stars that lived before the formation of the Solar
Is the behaviour of the isotope polonium-210 conditioned by the acidity of the waters?
The Acid Mine Drainage (AMD) is a phenomenon that takes place when sulphide minerals are exposed to atmospheric conditions. In the presence of oxygen and humidity, the sulphides are oxidised releasing the elements contained in the rocks
