Question

Radioactive isotopes are used in medicine to create images of internal

Answer 1

Answer:

The correct option is D) Fission

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.
