Al's got his funny bone working again...

I like that Al, sounds like a good way to teach a Welder the err of his ways.
Apatani -
It all depends on the code your working under and the fine print in the contract or agreed upon ITP (Inspection and Testing Plan).
Neither you or we can answer your question without that info.
Penalties for busting RT range from nothing - to fixing your own crap - to what Al said - and to immediate termination.
It all depends on the job specifics.
