Radioactive chlorine from 1950s nuclear weapon tests is still leaking from Antarctic ice sheets, according to worried scientists. A recent study claims that US nuclear bombs detonated 70 years ago … ...

Sulfur and chlorine isotopes in the atmosphere of Jupiter’s moon Io indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System, according to a ...

In a new study of Apollo moon rocks, geochemist Zachary Sharp of the University of New Mexico and colleagues measured the moon rocks' chlorine isotopes, or different forms of the chlorine atom ...

To measure the age and origin of the groundwater, 29 samples were collected from different wells during several field expeditions in Egypt. The researchers used the long-lived radioactive isotope ...

One approach for studying longer-term seismic activity on a fault, chlorine-36 (36 Cl) cosmogenic dating, is used to recover histories that can span more than 10,000 years. As slip along a fault ...

A nuclear warhead exploding near Christmas Island as part of Operation Dominic. These tests generated high levels of concentrations of isotopes like chlorine-36, which can also occur naturally.

The abundances of carbon isotopes can be used to investigate the purity of the source of foods like vanilla and honey, while isotopic measurements of elements such as nitrogen and chlorine can ...
