Depends entirely on the size and configuration.

Yep, one of the the reasons for SMD caps is that
the leads on conventional caps radiate at UHF+
frequencies.

The capacitor itself does not radiate ie what is
between the two plates but the size of a capacitor does matter when
releasing its charge that creates radiation. Since the time variance
of the charge release is what creats radiation it follows that the
size
of and the constrictions provided make a huge difference. (Read up on
Bernollis
and his work on fluids)
You can have a very small inductance with a very large capacitance
as the L.C. ratio stays intact but the time variance of energy
release
will certainly different in that moment of time when the radiation
pulse occurs
As with standard practices I am not taking into account the
inductance
of the capacitor plates themselves since it just provides an outlet
for posters to avoid repeat of past errors by changing the subject
