The Danger of Deadly Cosmic Explosions
... One factor that correlates well with likelihood of extinction in trilobites is the amount of time a typical organism spent in the water column. Trilobites that appear to have been pelagic as adults, or are inferred to have had a planktonic larval phase, were much more likely to go extinct15. In fact ...

Coupling and Collapse
... • If the particle moves in a radiation bath it will be suffering scattering by the many photons encountered on its path. • The scattering is anisotropic since the particle is moving in the direction defined by its velocity. • The particle will be hitting more photons in the front than in the back. • ...

... Alpha radiation consists of fast-moving particles that are thrown out of unstable nuclei when they decay. These are called alpha particles. Alpha particles are helium nuclei – helium atoms without their orbiting electrons. Figure 22.7 shows an alpha particle and the notation that is used to denote i ...

But, the nucleus contains only protons and neutrons. How can it give off an electron? In this kind of transmutation, a neutron becomes unstable. It ...

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.
