Radioactive isotopes have a variety of applications.

Generally, however, they are useful either because we can detect their radioactivity or we can use the energy they release.

First, try the practice questions to determine what you already know about radioisotopes.

Then, watch the video lesson to learn more about radioisotopes.

These are only some of the many applications of radioisotopes in our modern-day world.

Directions for This Lesson: In this lesson, you will learn about the uses of radioisotopes.

Iodine-131 has been used for treatment and detection in the system of thyroid disorders.

This is because humans that lack iodine in their diet will generally have problems with their thyroid, sometimes leading to an enlarged neck.

We know these steps because researchers followed the progress of the radioactive carbon-14 throughout the process.

Radioactive isotopes are useful for establishing the ages of various objects.

By comparing how much carbon-14 there is in the dead organism with the amount in a living one, the age of the dead organism can be estimated.
