uses of radioisotopes neutrons

Radioisotopes - Naturally occurring radioactive substances have high nucleon number. It is possible to make artificial radioactive substances by bombarding lighter nuclides with - particles, protons or neutrons. The radioactive substances produced in this manner are known as ..

These are slow moving neutrons. Slow moving neutrons are used to bring about the fission reaction. If we use fast moving neutrons, it will not be in contact with the fissionable material for sufficient time to bring about the fission reactio..

Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments, it was possible to calculate the char..

Applications of Radioactivity and Radioisotopes - Radioisotopes find numerous uses in different areas such as medicine, chemistry, biology, archaeology, agriculture, industry and engineeri..

(ii) The neutrons can be absorbed by substances which are not fissionable. Rods of boron or cadmium have the ability to absorb the desired number of neutrons. This ensures limited number of neutrons to be available for fission. (iii) The speed of the neutrons..

In 1936, Neils Bohr suggested that the nucleus might be like a droplet of dense liquid, composed of sub droplets of protons and neutrons. A uranium nucleus is spherical in shape. In this spherical nucleus, protons and neutrons are together because of the delicate balance existi..

All isotopes of a substance have the same chemical properties and behave in an identical manner. The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits. It has wide applications in various fields lik..

Radioisotopes are frequently used as tracers or tagged atoms in various fields. In tracer technique, a radioactive isotope is added to the reactants and its movement is studied by measuring radioactivity in different par..

In is used in the manufacture of paper, plastic and metal sheets. (Used to control the thickness of the sheets.) Radioisotopes can be used to estimate the amount of wear in bearings. Leaks in pipes may be traced by introducing a small quantity of ..
