Under what circumstances is it okay for a Muslim woman to be on TV?

It's plausible, at some point, that I might be asked to do a TV interview. My recent research is on a topic that might be picked up by the press. I'm unsure if this is appropriate as a Muslim woman. It clashes with the modesty expected of a Muslim woman. Yet, at the same time, it's not hard to find Muslim women on TV, so it's presumably sometimes acceptable. **Question**: Under what circumstances is it okay for a Muslim woman to be on TV?
