Positrons can do one of several things when interacting with ordinary matter:
Scatter elastically from an atom with hardly any loss of energy
Scatter inelastically from an atom leaving the atom in an excited state
Annihilate with an electron in an atom and emit two photons.
The probabilities of these possible outcomes vary considerably with the incident positron energy.
There is a raft of information on positron-matter interactions on the web; just google positron interactions with matter.
