What is the cosmic microwave background radiation
... Erik M. Leitch of the University of Chicago explains. The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. It is the residual heat of creation--the afterglow of the big bang ...

... lead to death. In minor cases the effect is similar to a burn. The amount of harm that radiation can cause is dependent on the number and energy of the particles. When a gamma photon is absorbed the whole photon is absorbed so one photon can ionize only one atom. However, the emmited electron has so ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
