Radionuclide Pollution:Definition|Prevention|Effect on human|Source|Types

Definition

• Radionuclide Pollution or Radionuclide Contamination is define as when the radioactive molecules are present on surface of solide,water,air or in human skin which is undesirable is called radionuclide contamination
• addition of radiation in environment from radioactive element is called Radionuclide Pollution.
• Radioactive pollution is like any other kind of pollution in which some unwanted elements are release into environment,this unwanted element is called Radioactive Pollution.
• Radioactive elements are spread through the earth atmosphere is called Fallout
• The measurement unit of Radioactivity is Disintegration or decays, per unit time.common unit of radioactivity is Becquerel, equal to 1 decay per second.and curie, equal to the 37 billion decay per second.

Source

The sources of radioactive pollution can be classified into two groups: natural and man made.

• Natural Source:
  1.Cosmic Radiation
  2.Internal Radiation
  3.Terrestrial Radiation
• Man Made Source:
  1.Production of or Research on Nuclear weapons:In production of nuclear weapon there used many radioactive element which have high health risk .
  2.Mining in radioactive ore: In mining involve crushing and processing of radioactive ore which creat radioactive waste ehich emits alpha particles
  3.Medical waste: In medical their used several type of radioactive isotopes either for treatment or diagnosis.
  4.Nuclear power plant: any accident in this plant can cause dangerous highly radioactive pollution.
  5.Industrial Radiography (X-ray imaging)

Type of Pollution

1. Continuous Pollution: This type pollution occurs in uranium mines,nuclear reactors,test lab etc.
2. Accidental Pollution: This type pollution occurs due to accidental exposure of radioactive elements inn environment from nuclear reactors etc.
3. Occasional Pollution: This occurs during the experiment or test of Nuclear Substances.

Effect of Radiation On Human

• On expose to radiation it can cause skin diseases in human.
• Exposure to high radiation or long time exposure can damage the DNA structure.
• The rapidly growing or dividing cells are highly sensitive to radioactive molecule.
• rays from radioactive element can cause hair loss,heart failure,brain cell damage,burn,etc.

Prevention

• Nuclear Medicines and nuclear therapy should be applied when absolutely necessary.
• In nuclear mines wet drilling my be employed.
• Fission reaction should be minimised.
• Leakages in nuclear reactors,careless transport,use of radioactive isotopes have to be totally stop.
• Waste disposal should be effective and careful.
