Top 10 Questions for Radioisotope Technician Interview

1. Can you describe the process of radioisotope production and how it is used in medical imaging?

Radioisotope production is the process of creating radioactive isotopes, which are atoms with an unstable nucleus. These isotopes are used in medical imaging to create images of the inside of the body. The process of radioisotope production typically involves bombarding a stable atom with particles such as protons or neutrons. This bombardment causes the atom to capture the particles and become a radioactive isotope.

• The radioactive isotope is then used in medical imaging by injecting it into the body. The isotope will then travel to the target organ or tissue and emit radiation, which can be detected by a scanner.
• The scanner will then create an image of the target organ or tissue based on the amount of radiation that was detected.

2. What are the different types of radioisotopes used in medical imaging?
