A basic explanation of Cherenkov Radiation from Encyclopedia Britannica.
Electromagnetic radiation emitted when a charged particle gives off energy as it moves through a transparent medium faster than the speed of light in that medium.
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.
A range of very good information on various radiation risks such as mobiles and power lines.
Page giving the Stephan-Boltzman radiation equation.
Comprehensive info on the three most important kinds of nuclear radiation and their uses.
