It depends on the type of scan but by far the most common scan uses "gamma" rays to get a picture. The radionuclide used is Tc99m which gives off gamma rays at 140 kEV, a very suitable energy level for the cameras used in nuclear medicine.

Nuclear medicine scan?
For most nuclear imaging studies, radionuclide is injected into the patient and the images are taken with a gamma camera suspended above the patient who will be lying on a table. The camera detects the gamma rays emitted from the radionuclide in the patient's body and uses this information to produce an image that shows the distribution of the radionuclide within the body. The image is recorded on film and is called a radionuclide scan.
How is a technetium heart scan done?
The isotope is injected into a vein and absorbed by healthy tissue at a known rate during a certain time period. The radionuclide detector, in this case a gamma scintillation camera, picks up the gamma rays emitted by the isotope.
Is a cat scan nuclear fusion or nuclear fission?
Neither, a CAT scan is one where computers are used to synthesise an image, but the radiation used is usually X-rays, though positron emission can be used, in this case it will be using appropriate radiation sources. Fusion and fission don't come into it.
Which ones is not a nuclear medicine scan?
Gallium scan
What is the medical term meaning nuclear scan of the gallbladder?

Why it is not advisable to have X rays and CT scan exposures in relatively short period?
because RADIATION can come from X-rays & CT scan, which can cause cancer, & mutations in the later generation

How does a PET Scan use Radioisotope decay?
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
What is the purpose of akidney nuclear medicine scan?
the kidney nuclear medicine scan is unique in that it reveals how the kidneys are functioning. This is valuable information in helping a doctor make a diagnosis.
