Radiation in live broadcast affected actor (6)

I believe the answer is:

luvvie

I'm a little stuck... Click here to teach me more about this clue!

'affected actor' is the definition.
'luvvie' can be an answer for 'actor' (I've seen this before). I'm not certain of the 'affected' bit.

'radiation in live broadcast' is the wordplay.
'radiation' becomes 'uv' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
'broadcast' indicates an anagram (letters scattered or cast around).
'live' anagrammed gives 'lvie'.
'uv' put into 'lvie' is 'LUVVIE'.

Can you help me to learn more?

(Other definitions for luvvie that I've seen before include "18, 5 [LAURENCE OLIVIER] for example" , "Theatrical type" , "affected actor, perhaps" .)
