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 ...

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

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 ...

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, ...

For the first time, researchers have demonstrated that certain lichen species can survive Mars-like conditions, including ...

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 ...

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 ...

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 ...

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 ...

The addition of concurrent cisplatin to adjuvant radiation therapy conferred no benefit to women with intermediate-risk, ...
