The detection and study of isotopes, atoms of the same element that have different numbers of neutrons, could expand the ...

Every second in your body, thousands of tiny isotopes are bursting with radioactive decay. And, all around you, imperceptible gamma rays explode in a brilliant but invisible lightshow. And they've ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. A battery made of diamonds could power devices for thousands of years, scientists have announced. This battery would be ...

Radioactivity, discovered more than 100 years ago and studied by physicists ever since, would seem to be a relatively closed subject in science. However, since the 1960s, the pursuit of at least one ...

The rise of a new generation of radiotherapies means we will soon need much greater quantities of radioactive atoms. That's ...

Through measurement of geoneutrinos, emitted during the radioactive decay of isotopes in Earth's mantle, the KamLAND Collaboration 2 demonstrates that radioactive decay contributes only around half of ...

Radioactive isotopes have been discovered by Russia's state weather agency in test samples more than two weeks after a mysterious and deadly explosion earlier this month at a naval weapons testing ...

Radioactive elements on Earth are like geological watches. A radioactive isotope of carbon is used to date human civilizations, among other things, because we know that its half-life is precisely ...

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could ...

The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...
