<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">give off heat</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for radiate that I've seen before include "A tirade (anag)" , "Beam brightly, spread heat" , "broadcast" , "Travel from centre in all directions" , "Emit rays; diverge" .)
