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 ...
Unstable atoms emit fast-moving particles that can damage cells in the human body. Some atoms are far more unstable than ...
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 ...
An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the periodic table and having almost identical chemical behavior, but ...
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 ...
Radiometric dating, utilizing the predictable decay rates of radioactive isotopes within rocks and other materials, is the primary method for determining the age of geological samples. Multiple ...
On October 10, 2006, Ken Moody answered selected viewer questions about the ongoing quest to forge new chemical elements and the search for a so-called Island of Stability. Please note we are no ...
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 ...
University of Wisconsin-Madison Professor Zachary Morris discusses his research into the field of theranostics and the “team ...
MOSCOW, Aug 26 (Reuters) - Russia's state weather agency said on Monday it had found the radioactive isotopes of strontium, barium and lanthanum in test samples after a mysterious accident during a ...
