A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has been demonstrated by researchers at the US National Institute of Standards ...

Discover how Rydberg atoms can measure temperature with unmatched precision. Read more on this breakthrough technology.

The nuclei of other atoms are unstable. These nuclei undergo change spontaneously, that is, without outside help. When unstable nuclei undergo change they give off radiation. Atoms which have unstable ...

Fallout from nuclear explosives testing, and small quantities of radioactive materials released to the environment from coal and nuclear power plants, are also sources of radiation exposure to man.

Scientists have been arguing about the health risks from radiation since the end of the 19th century, when radioactivity was first discovered. Today, with electricity demand soaring and AI companies ...

Fallout from nuclear explosives testing, and small quantities of radioactive materials released to the environment from coal and nuclear power plants, are also sources of radiation exposure to man.

The absorption of radiation can be analysed by an ‘absorption spectrum’. The different black lines show the frequencies absorbed by electrons in atoms. An excited electron can fall to a lower ...

NIST scientists have developed a new method for measuring temperature extremely accurately by using giant “Rydberg” atoms.

In their ability to penetrate matter and displace electrons in atoms and molecules, the various forms of this radiation have deep significance for science, technology and the future of man ...

While it may not sound like a major leap, this approach offers one big advantage: killing cancerous cells while doing less ...
