Observations from high-flying aircraft revealed that thunderclouds act as natural particle accelerators, emitting energetic ...

Cosmic particles with phenomenal energy have puzzled scientists for decades. A new theory may finally unveil their origin.

Researchers at the European XFEL have developed a new device for X-ray measurements at high photon energies—a so-called Laue ...

The body absorbs some of the X rays’ energy. The very low radiation doses absorbed during imaging procedures generally produce no adverse effects, but it is still recommended to reduce the doses as ...

These rays are produced by the hottest and most energetic objects in the universe, such as supernovae, neutron stars, and black holes. Because of their high energy, gamma rays can penetrate ...

Each element emits X-rays at unique energy levels, allowing for the identification and quantification of the elements present. When the electron beam interacts with the atoms in the sample, it excites ...

A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino ...

This module is about the measurement of bone density and body composition using the dual-energy X-ray absorptiometry (DXA) technique. DXA differs from many body composition techniques commonly used in ...
