NUCLEAR POWER AND ITS DANGEROUS EFFECTS ON HUMANS

NUCLEAR ENERGY

Nuclear energy is the energy in the nucleons  of   atom The nucleus of an atom contains positively charged protons an neutral neutrons.Negatively charged particles (electrons)  revolve around the nucleus. A lot  of energy is stored in the bonds that hold atoms together. Nuclear fission and fusion are  the  two  processes  which  release  the  energy  stored in the nucleus.

 

                                                                                                  NUCLEAR FUSION

Nuclear Fusion is the way of combining the atoms to make a new atom. Inside the sun, hydrogen atoms combine together to produce Helium. Because Helium does not need that much energy to hold it together, the extra energy that is produced is released as heat and light.

 

                                                                                            NUCLEAR FISSION 

Nuclear Fission is the way of splitting an atom into two smaller atoms. Because of their size, the smaller atoms do not need as much as much energy to hold them together as the larger atom, so the extra energy is released as heat and radiation.

 

                                                                                       USE OF NUCLEAR RADIATIONS

Nuclear Radiation can either be extremely beneficial or extremely dangerous. It just depends on how it is used. In cases where it is beneficial. It is used in X-RAY machines for diagnosis and nuclear power plants for generating whereas it is also used in nuclear weapons-a dangerous source of destruction.

 

                                                                                ADVANTAGES OF NUCLEAR ENERGY

Nuclear Energy is produced in large quantities using small amount of fuel. It does not produce a lot of waste and does not need pollutants into the atmosphere. It can be used to produce large amount of energy by very small decay of matter.

 

                                                                                DISADVANTAGES OF NUCLEAR ENERGY

Nuclear Plants have to be protected as any leak of radioactive substance can be extremely harmful for all living organisms. Whatever, waste is generated, needs to be buried and sealed for Hundreds of years until it losses its radioactivity.

 

                                                                                WORST NUCLEAR DISASTER IN WORLD

CHERNOBYL NUCLEAR ACCIDENT:-

               The Chernobyl nuclear accident which was held in April, 1986 is regarded as the worst accident in history. It was the first nuclear accident to be classified as “major accident” by International Atomic Energy Agency. Several people died due to radiation exposure and people who lived in the vicinity were relocated to other areas due to high levels of radioactive communication surrounding the reactor site.
