Nuclear diagnostic devices such as X-Rays, CT Scans, and MRIs have revolutionized medicine, and they give doctors the ability to examine their patients thoroughly. X-rays are a very routine procedure used on a daily basis, and MRIs provide a wealth of information without requiring doctors to anesthetize their patients or subject them to unnecessary surgical procedures. Prolonged radiation exposure is harmful to humans, but short-term exposure is justified if it leads to successful treatment outcomes. The technicians who perform the procedures are around radiation every day, and it’s important that they’re shielded from harmful gamma rays when they do their jobs.
