Question

Radioactive isotopes are used in medicine to create images of internal

structures of the human body. What process is used to create theses
isotopes?
A. Gamma decay
B. Fusion
C. Alpha decay
D. Fission

Answer 1

The correct option is D) Fission

Step-by-step explanation:

There are several methods through which Radioactive isotopes are created.

1. Using a nuclear reactor that has a field of neutrons, insert a stable sample such as Lutetium-176. When it gets bombarded with neutrons, it acquires some, and fission is said to have occurred. Note that when Lutetium-176 acquires a neutron, it becomes radioactive Lu-177.
2. Fission is also used to create Fluorine-18. To obtain the same, you need to bombard pure or enriched [
   `^(18) O`] water with ~18 MeV protons which are high energy in nature. The bombarding is achieved using a cyclotron or an accelerator.
