Yes it radiates. How much depends on the lengths of the wires.
The point at which you connect the coax to the two-wire line is a bit like a dipole feedpoint, with about half the voltage applied to it. This is why:
The voltages on the lines look like this at the junction. (Remember when you zoom in to a region much smaller than a wavelength, there's no RF ...

The characteristic of coax that causes current to split up between the load or antenna and the outside of the braid is the fact that the braid has two surfaces, inner and outer.
Ladder line has two wires with no inner or outer, the conductors only have one surface each and so at the ends there is no where for the current to split up to, as with coax.
If a ...

The thing about the coax that I didn't know for the longest time is that the inside of the shield and the outside of the shield are essentially 2 separate wires, that are only connected at the ends (or anywhere the shield opens up). This is because of the skin effect at the frequency and thickness of the shield. When you connect the coax to ladder line, you ...
