JAIN PHILOSOPHY & DIODEER SCIENCE are naturally radioactive, while hydrogen bombs and atom bombs are typical examples of producing radio 1 activity artificially. The process of radioactivity consists of the emission of an electron or proton, (the constituent clements of atom), either spontaneously or by artificial methods, with or without the accompaniment of sound hke that of the explosion of a "bomb Sometimes, radio active material is diffused in large areas. This diffusion is called 'radiation'. .,
Uranium which is the last of the 92 natural elements emits 3 kinds of radiations They are named as 'alpha', 'beta' and 'gamma rays respectively When an atom of uranium has lost three alpha particles, at is transformed into an atom of Radium, which itself is a radioactive element. It also emits all three kinds of radiations constantly. When it loses five alpha particles, it does not remain radium but is changed into lead All the three radiations, 'alpha', 'beta' and 'gamma rays are of different nature 'Beta' particle is the same as an electron, but is emitted from the nucleus of anotom. 'Alpha' particle consists of two protons and two neutrons and is the same as atomic nucleus of Helium 'Gamma' rays are similar to x-rays but much more powerful. The wave length of an X-ray is ten millionth part of an inch, while, gamma rays have a wave length of a thousand millionth part of an inch. The effect of the abovementioned variations from uranium is the reduction - of the number of electrons and protons from uranium
