Pollution

Radioactive Pollution

Pollution 

Pollution means presence of anything in the system which is not naturally found in that or presence in unproportionate manner. It is the process of making the environment land water and air dirty by adding harmful substance to it which causes imbalance in the environment.
Environmental pollution is a serious problem of the industrialized societies. The industrial development & the green revolution have adversely affected the environment. Day by day pollution has been increasing & imbalance has threatened the very survival of all forms of life. It is threat to the whole world. People have converted the life supporting system of the entire living world into their own resources and have vastly disturbed the natural ecological balance. It is defined as the unfavourable alteration of our surroundings. In India allay the source of water lie rivers lakes ponds and wells have been polluted and are unfit for drinking. As a result of the increased use of fertilizers, the rivers seas and oceans have become contaminated with harmful pollutants. Pollution is a product of people activities which directly or indirectly  responsible for the changes in environment. All changes in the physical, chemical or biological characteristics of land, air, or water than harm human life and other living things. Population explosion, rapid industrialisation deforestation unplanned urbanization scientific and technological advancement. 

Pollution occurs in different forms like air, water, soil, radioactive, noise, heat, light. All forms of pollution have two sources of matter like point and non-point sources. The point sources are easy to find while the non-point sources are hard to find and hard to control. 

According to the physics Radiation the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization. The radiation is not very much fruitful for animals and humans, however modern technology used it in several medical applications. Yes, It is harmful but in higher amount or frequency below a limit it is useful. Here I must say about the electromagnetic waves coming from sun which is reflected back in the universe by earth's magnetic field.

Radiation as a Pollution 

It is highly dangerous when it occurs. It can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It can cause cancer, infertility, blindness, defects at the time of birth; can sterile soil and affect air and water. Radioactivity is radioactive decay or emission of particles (neuron, proton or heavier particles) from an atom or nucleus. Recently radioactive elements are also used in research and medicine. These pollutants are directly linked to nuclear energy. It contamination also call radiological contamination, is the deposition off or presence of radioactive substances on surfaces or within solids, liquids or gases. The most dangerous long-lived radio nuclides are those emitted by nuclear reactors. It’s most popular use in the past has been in wars where it destroyed entire cities in one go; however, today it is widely used as an energy source to fuel electricity. It may be due to electromagnetic radiation, nuclear radiation, or cosmic radiation.
Electromagnetic radiation occurs through X-rays, gamma rays, UV rays visible light, infrared rays and radio waves.
Nuclear radiation pollution occurs when radioactive atoms like uranium, thorium etc. release radiation in the form of alpha and beta particles. Nuclear radiation also occurs when radioactive elements are produced artificially in nuclear reactors and particle accelerators.
Cosmic radiation takes place due to high energy particles invading the earth and its atmosphere from outer space and the sun. Cosmic rays consist of electrons, protons, helium nuclei, hydrogen nuclei, and the nuclei belonging to heavier elements like carbon and oxygen.

      Sources

  • Nuclear power plant accidents or leakage
  • Improper nuclear waste disposal
  • Uranium mining operations

     Effect


  • Cancer
  • Sterilization
  • Birth defect
  • Mutations which have greater impact on our physique 

     Remedies


  • The protective garments must be worn
  • The natural radiation must be at the permissible limits

  1. No its not a common pollution

    1. Of course it's not a common pollution but people should be aware about this too.
