Radiation Pollution
It is unfortunate that harmful radiations cause severe pollution but they cannot be seen or observed by eyes and are difficult to judge, unless present in such concentrations so as to cause an acute effect. These are wastes without weight. The main sources of radioactive pollution are:
- Nuclear testing,
- Blast of atomic bombs,
- Exhaust of nuclear power plants or accidents in them, and medical and industrial use of radio isotopes. The stores of fossil fuels in the world are limited therefore, more and more nuclear fission reactors are installed as they are clean and cheap source of power generation. However, two problems are associated with them.
- They produce increasingly large radioactive waste and
- Pose a greater risk of accident.
