A short description of the Van Allen radiation belt that surrounds the Earth.
Article from the Economist about the idea of reducing the number of electrons in the Van Allen belts.
An explanation of the two huge doughnut-shaped rings, called Van Allen Belts, containing charged particles collected from the solar wind. Also includes a little on the history of their discovery.
Radiation can interact with surrounding matter to produce positively and negatively charged particles (a type of electricity). This process is called ionisation, hence the term ionizing radiation.
When moving charges spiral in a magnetic field, they produce radiation as a result of their accelerations which is called synchrotron radiation.
Blackbody radiation refers to an object or system which absorbs all radiation incident upon it and re-radiates energy which is characteristic of this radiating system.
Units of radiation, description of risk of radiation, comparing old and new units with good links to other relevant parts of the site.
This fact sheet describes ionizing radiation, how it behaves and how it can affect human health. Three types of ionizing radiation are alpha particles, beta particles, and gamma rays.
Page giving the Stephan-Boltzman radiation equation.
A range of very good information on various radiation risks such as mobiles and power lines.
