A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When..

Breeder Reactors - Natural uranium contains very little (0.72%) of its fissionable isotope 2 3 5 U needs to be enriched in the latter to be useful as a fuel in nuclear reactor. A breeder reactor is one that produces more fissionable nuclei than it consumes. Another serious problem about U-235 is th..

Radioactivity - It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur due to any external provocation ..

When certain metals are heated to a high temperature, they emit thermions (electrons) and the phenomenon is called thermionic emission Cathode rays are a stream of negatively charged particles emitted from the cathode of an evacuated bulb, when a voltage of nearly 3000 volts given across the t..

Radioactive elements are those, which emit invisible radiations of their own accord. This is called radioactivity. Some typical examples of radioactive elements are uranium, thorium, plutonium, polonium etc. Radiations emitted by radioactive elements consists of Alpha particle..
