He concluded that the radiation must be coming from above the atmosphere. For this, he was awarded the Nobel Prize in 1936. The name “cosmic ray” itself dates to 1925, when Nobel laureate and former ...

This is because the electromagnetic radiation produced by blazars extends from the radio range through the optical, ultraviolet and X-ray regions to gamma radiation of the highest energies.

Radiation hardened devices are built to withstand cosmic rays and other natural electromagnetic radiation, as well as nuclear explosions. The effects of such radiation can be a temporary ...

Called electromagnetic radiation, such waves travel at the speed of light and bring us almost all the information we have about the universe. Gamma rays are much shorter in wavelength than visible ...

Ultraviolet (UV) radiation can cause ... and other people working with X-rays must take precautions to reduce this risk. Each region of the electromagnetic spectrum has a range of wavelengths ...

The radiation we receive from outer space is called cosmic radiation or cosmic rays. We also receive exposure from man-made radiation, such as X-rays, radiation used to diagnose diseases and for ...

Changes in atoms and their nuclei can cause electromagnetic waves to be generated or absorbed. Gamma rays are produced by changes in the nucleus of an atom. They are a form of nuclear radiation.
