Chapter 2 Observing the Electromagnetic Spectrum
... Emission from the night sky plays an important part in observational astronomy and seriously affects our ability to detect faint objects. Reactions in the upper atmosphere that result in radiation are known as airglow or nightglow. Electrons recombining with ions (e.g. O, Na, O2 , OH) at typical alt ...

... absorption maximum at 520 nm disappears progressively and the final spectrum is close to the surface plasmon spectrum of pure palladium clusters. The spectral evolution indicates indeed that the cluster composition changes when the dose increases from almost pure gold clusters (0-3.5 kGy) to cluster ...

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.
