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

A startup energy company, called Marathon Fusion, may soon be living out the dream of alchemists from the Middle Ages. In a ...

For the first time, researchers have observed aluminium-20, a previously unknown and unstable isotope that decays via the ...

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.

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

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.

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 ...
