[Doctor Who] What would happen if an atomic bomb went off inside the TARDIS?

We all know how tough the TARDIS is from the outside, but what would happen if it was attacked from the inside? 


Are the rooms tough enough to withstand the blast? What would be seen in the gaps between the rooms?

The interior of a TARDIS is a sort of pocket dimension unto itself-- not quite outside of the universe, but nothing exists "between" the rooms per se, not even space.

The TARDIS itself is huge-- you could wander for years inside it. It would probably survive the blast if you didn't destroy anything vital like the Eye of Harmony. If you did destroy vital components it would probably go inert.
