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.
