The relevant spec text is in several places.

For radio buttons in particular:

   http://www.whatwg.org/specs/web-apps/current-work/#radio-button-state

# If the element is mutable, then: The pre-click activation steps consist 
# of setting the element's checkedness to true. The canceled activation 
# steps consist of setting the element's checkedness to false. The 
# activation behavior is to fire a simple event called change at the 
# element.

Most of the terms in that paragraph are to do with (and are hyperlinked 
to) the algorithms defined in:

   http://www.whatwg.org/specs/web-apps/current-work/#interactive-content

Please let me know if that doesn't make sense, and I'll try to clarify it.

HTH,
