Radioactive wastes Nuclear energy was initially hailed as a non - polluting way for generating electricity. But, later it was realised that the use of nuclear energy has 2 very serious inherent problems, 1) Accidental leakage 2) Safe disposal of radioactive wastes.
Radiation given off by nuclear waste is extremely damaging to biological organisms, because it causes mutations to occur at a very high rate. High doses of nuclear waste is lethal. Lower doses of nuclear waste causes various disorders. (frequently cancer) Therefore it has to be dealt with caution! After sufficient pre treatment of nuclear wastes, it has been recommended to store them in shielded containers buried with I n the rocks, about 500m deep below the earths surface.
What is GREEN HOUSE EFFECT and GLOBAL WARMING??? Have you ever heard about GREEN HOUSE???
The term green house effect has been derived from a phenomenon that occurs in a greenhouse. A greenhouse (also called a glasshouse) is a structure with walls and roof made mainly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown. The glass panel of the green house lets the light in but does not allow heat to escape.
It warms up very much. Can u imagine yourself being inside a car that has been parked in the sun for a few hours??? It must be very hot!
1) Carbon dioxide 2) Methane Are commonly known as green house gases because they are responsibe for the greenhouse effect.
Green house effect is a naturally occurring phenomenon that is responsible for heating of earths surface and atmosphere. .The average temperature at surface of earth is estimated to be about -18 degree Celsius with out green house effect rather than the present average of 15 degree Celsius. Clouds and gases reflect about one fourth of the incoming solar radiation, and absorb some of it but almost half of incoming solar radiation falls on earths surface heating it, while a small proportion is reflected back.
