Admob banner under Alert dialog: does it violate any Admob policy

I have an activity page with an admob banner on the top of the activity page. The page also contain a button. When the button is clicked an alert dialog will overlay the activity page containing the admob banner.

Is it allow or does it violate any admob policy?

Thank you in advance
