    You need to give loads more background than this.

    If I had to guess.....

    Well, this is dependent on if the x-ray is from a nucleus or not - a gamma, I believe, is from the nucleus and if I remember correctly an x-ray is from the electron shells?

    anyway

    the photon would be absorbed by something - nucleus or electron, and in the case of the electron, it would disassociate from the atom. In the case of the nucleus, it would lead to gamma decay, emitting another photon (it would excite a neutron/proton to a higher energy level in the nucleus, which would in a finite time afterwards, re-emit it.)
