What can radioisotopes do?

1. Radiography, which shows the inside of an object on a photograph.

2. Application of measurement technology, measurement of paleontological age, monitoring and control of material thickness in the production process.

3. Use radioactive isotopes as tracers.

4, with radioisotope energy, as spacecraft, artificial heart energy, etc.

5. Use the lethality of radioactive isotopes to turn evil into good, treat cancer, sterilize and catalyze reactions.

The longer the half-life, the slower it decays, and the shorter the half-life, the faster it decays. The half-life is a characteristic constant of radioisotopes. Different radioisotopes have different half-lives and emit different kinds and amounts of radiation as they decay.
