Introduction<br /><ul><li>Nuclear Pollution happens when Radioactive element come into contact with other elements in environment & emits “Alpha & Gamma rays”(Short Wave Electromagnetic Rays) Which is serious threat to living organisms.
The Phenomenon of “Nuclear Fission” creates a nuclear pollution.
Due to “Nuclear Fission” 15% to 20% Nuclear Particles enter into “Stratosphere”.
Almost 5% Nuclear Particles enter into “Troposphere”.</li></li></ul><li>Nuclear fission<br />

This dispersed large quantities of radioactive fuel and core materials into the atmosphere and ignited the combustible graphite moderator. The burning graphite moderator increased the emission of radioactive particles, carried by the smoke, as the reactor had not been encased by any kind of hard containment vessel. The accident occurred during an experiment scheduled to test a potential safety emergency core cooling feature, which took place during the normal shutdown procedure.<br /> The accident raised concerns about the safety of the Soviet nuclear power industry, as well as nuclear power in general, slowing its expansion for a number of years and forcing the Soviet government to become less secretive about its procedures.<br />
