PSMA PET scan is equivalent to about 4 years background radiation. (Most other types of PET scan are more.)
No radiation from MRI scans (it's a magnetic field, not an ionising field).
CT scan depends which part of the body. Abdomen/pelvis without contrast is equivalent to about 2.5 years background radiation, or double that if done with and without contrast.
Technetium-99m nuclear bone scan is equivalent to about 2 years background radiation.
Chest X-ray is equivalent to about 0.1 years background radiation.
Each time you are offered a scan, the associated risks have been considered and the scan was only offered if the benefits outweigh the risks.
