neutron radioactivity

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 du..

Radioactive Dating - All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or..

This technique is of gaining importance in analytical chemistry. In this technique, the sample containing very small amount of the stable isotope of the element to be investigated is bombarded with neutrons. This element is activated into its radioactive isotope. The radio..

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 disintegrat..

(this is not very common and occurs in case of nuclei with low n/p ratio and having insufficient energy for positron emissio..

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 man..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more efficient in causing nucl..
