The present paper aims to discuss the possible dissipative mechanisms acting in a coronal prominence. These mechanism are discussed within the context of spatial damping of linear compressional waves. The obtained results show that the dominant mechanism is thermal radiation provided the supposition of optically thin prominence is valid. Damping due to thermal conduction is a viable attenuation mechanism provided the wavelength of the waves is short.
