Give three peaceful uses of nuclear reaction and explain their operations. – NABTEB QUESTION

Peaceful uses of nuclear reaction:

1. Medical field for radiotherapy: This uses radioisotopes which are by-products of fission reactions. After injection into the body their movement through the body organs are monitored.

2. Radioisotopes are used in agriculture as radioactive tracers and preservatives.

3. Electricity generation from a Nuclear power plant.

4. For powering space crafts and submarine. Based on small nuclear power reactors.

5. Radiotherapy (medical use) is the use of radioactive emissions to treat patients. The emissions destroy unwanted cells which are present in cancer patients capsules containing some radioactive isotopes (e.g 60C0) of appropriate activity and half-life are implanted near the unwanted growth and left there for a carefully calculated time.

6. Radioactive dating to find the age of a geological formation or when an archaeological artifact was made. Here carbon dating or uranium dating is used.
