**nuclear fission**of atoms which is then used to generate electricity.

4. Uses of Nuclear Energy

# What is Nuclear Fission?

**nuclear fission**.

**Einstein's**mass-energy equivalent relation.

Where c is the speed of light, which is nearly 299792458 m/s.

## What is Nuclear Energy?

**nuclear energy**. In 1905 on the basis of the theory of relativity Einstein suggests that mass and energy are interchangeable. So he gave a mass-energy equivalent relation, which is given above. This relationship between mass and energy is used to determine how much energy can be produced from the destroyed mass.

### Calculation of Nuclear Energy

**atomic mass unit (a.m.u)**. This unit is related to the S.I unit of mass (kg) is like that

If This much energy is converted into

**MeV**then it will be

This means that if 1 a.m.u mass is lost in nuclear fission, this lost mass will produce nearly 931MeV of nuclear energy.

### Uses of Nuclear Energy

If we look at the use of nuclear energy then humans have used this energy in two ways since they came to know about it. This nuclear energy has been used in both destructive and constructive ways. The way in which human consciousness has evolved has gradually shifted from the destructive use of nuclear energy to constructive use of it.

In the 1940s, during the Second World War research initially focused on producing bombs out of nuclear energy. The focus then shifted to the peaceful use of nuclear energy by controlling it for power generation in the 1950s. Nuclear energy is now used in a variety of ways, such as industrial use, transportation, agriculture, and the medical field.

**1. Uses of Nuclear Energy in Industry**

**Industrial tracers:**Many radioisotopes are used as tracers to monitor fluid flow and filtration, detect leakage, and gauge engine wear.

**Inspection and instrumentation:**Many radioactive substances are used to inspect metal parts and the integrity of welds across a range of industries.

**Carbon dating:**For geologists, anthropologists, hydrologists, and archaeologists, the process of carbon dating play a very important role in determining the age of rocks and other materials.

**2. Uses of Nuclear Energy in Transportation**

**Nuclear-powered ships:**Many small nuclear power plants are used to generate electricity in submarines.

**Nuclear reactors for space:**In many space missions RTGs (Radioisotope Thermal Generators) are used where radioactive substances like plutonium-238 used to generate electricity.

**3. Uses of Nuclear Energy in Agriculture**

In various fields of agriculture such as Plant Mutazian Breeding, Fertilizers, Insect Control, Consumer Products, Food Irradiation, the importance of this nuclear energy is essential.

**4. Uses of Nuclear Energy in the Medical field**

The importance of this nuclear energy in various fields of treatment such as diagnosis, therapy, sterilization is also essential.
