Collapse in gravitaion field

Hi,

I've know that accelerated charge generates electromagnetic radiation which eventually should cause the electron to crash in to the atom nuclear, until Bohr atom model.
Suppose that we have a mass which cause to gravitation field.
If this mass will be accelerated, will it radiate gravitational field? and furthermore, will it energy will be lost eventually (In this case I guess that Bohr's model is not relevant) ?


Thanks,
Adam.
