Radioactive Isotopes

Chandra's Atmospheric Composition Explorer-2 (CHACE-2) payload aboard the Chandrayaan-2 Orbiter has detected Argon-40, said ISRO.

It was, North Korea insists, a successful test of the "H-bomb of justice." "One's destiny should be defended," Pyongyang declared in a statement issued shortly after the Wednesday blast, saying it had "proudly joined the advanced ranks of nuclear weapons states."

Just in time for the new year, researchers at the Department of Energy's Oak Ridge National Laboratory have unveiled the fruits of a different kind of energy research: For the first time in nearly three decades, they've produced a special fuel that scientists hope will power the future exploration of deep space.

An unknown number of Londoners might have been put at risk by the 2006 poisoning of ex-KGB agent Alexander Litvinenko with a radioactive isotope, which amounted to "a nuclear attack on the streets" of the British capital, an inquiry heard on Thursday.
