Prof. Peter G. Bergmann, a coworker of Einstein, uses both terms in his book "The riddle of gravitation", whose Italian version I have edited.

is the term gravitational

is the term gravitational waves appropriate for waves in spacetime and the term gravitational radiation appropriate for the emission of gravitons?

'Gravitational wave' is a term from general relativity to describe gravity in terms of curved spacetime, while the term 'graviton' implies a quantum theory of gravity... and the quantum mechanics of the Standard Model is still being worked out regarding gravity and compatibility of a quantum theory of gravity with general relativity...

edit – as is the case with light, and as Tullio alluded to for the case of gravitation, the term 'radiation' can be used to describe the propagation of both waves and particles...
