The positrons produce gamma rays when they are finally annihilated in the target, which will ultimately end up as heat in your radiation shielding.
The positron source is a radioactive isotope that naturally emits positrons. This means that the total amount of energy involved will be quite low (very few positrons). It's a testament to the engineering skill of the people who built the microscope that they can get the results they do, with such a small number of positrons.
The radioactive isotope is probably produced by sticking a container of appropriate source material into a fission reactor's core for a few hours/days/weeks. That's how most medical isotopes are produced.
