What a gamma camera does

Cross-sectional diagram of a gamma camera showing a patient with a radioactive tracer, a lead collimator, a NaI(Tl) scintillator, a light guide, a photomultiplier tube array, and a computer building a 2D image

Gamma cameras detect gamma photons emitted by a radioactive tracer inside the patient. The camera is a passive detector, so unlike an X-ray machine it does not send radiation into the body.
