Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.

Our analytical XRD instrument utilises X-ray radiation to investigate the structure of crystallised biomolecular assemblies through X-ray diffraction (XRD). X-ray radiation is a type of ionising ...

Scientists have detected radio signals from hot gas surrounding a supermassive black hole that existed 12.9 billion years ago ...

Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from black hole surroundings. The radiation originates ...

Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found in some drugs, it is not yet well understood. Using an innovative technique ...

X-Ray radiation units used at Purdue University may be classified as either analytical or diagnostic. Both types of systems are sources of ionization radiation when they are operational; therefore, ...

"Many supermassive black holes may lie concealed within dusty regions of the early universe, undetected," said astronomer Takafumi Tsukui.

While we typically encourage hackers to make their own tools or machines when practical, x-ray machines don’t usually make that list. Despite the risk of radiation, [William Osman] has done just ...

Authorization to purchase, store, use or dispose of an x-ray machine must be obtained from the Radiation Safety Committee or the Radiation Safety Officer (RSO). Certain instrumentation, machines, and ...

Adverse effects from radiation dose absorbed in diagnostic practice are rare. For example, the radiation dose absorbed from a simple X ray examination such as a chest X ray (radiograph) or an X ray of ...

An curved arrow pointing right. People are often concerned about how radiation exposure may be affecting their health. It's true that extreme exposure can do terrible things to your body ...

US researchers have come up with a new way to get better quality X-ray images without having to use more radiation, which increases risk for patients. US researchers have come up with a new way to ...
