Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying ...

Beyond plans to return astronauts to the moon for the first time since the Apollo Era, NASA and other space agencies have ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through ...

The 311-gram space rock was discovered in 2023 and is known as the Northwest Africa 16286 meteorite — and based on the decay ...

Physicists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have reported the first observation and spectroscopy of aluminium-20, a ...

The debate is between those who see a path to making nuclear waste clean again and those who advocate a more cautious ...

How to date rock Dating rocks involves using radiometric techniques that harness the natural and spontaneous radioactive decay of certain elements in the rock, which acts as a type of clock.

Like most nuclear plants, the six-reactor Zaporizhzhia facility is situated near a body of water that serves as its ultimate heat sink (UHS), an assured supply of water to its “essential service water ...

Breathing in radon can be dangerous. Its radioactive particles decay in the lungs, releasing small bursts of radiation. Research shows this can damage lung tissue and cause lung cancer.

The amount of time it takes for half of a radioactive tracer to decay is called its half-life. Tl-201 has a half-life of about 3 days, whereas Tc-99 has a half-life of about 6 hours.

In 1947, Kix cereal ran a promotion for an "Atomic Bomb Ring" that contained radioactive polonium-210, one of the deadliest ...
