Water when irradiated with x-rays or γ-rays results into the formation of high energy electrons. These high energy electrons are known as Hydrated Electron. During collisions these electrons lose some part of energy and are said to become thermalised. The electron which is thermalised get ...

Formation of free radicals: The ionic products which are formed during Radiolysis of Water Vapour are very reactive. So they get recombined to form free radicals. The formation of free radicals is discussed below: H2O+ + e-------> •OH + •H H+ + H2O + e------->H3O+ + e------> 2H• ...

Formation of ionic products: During Radiolysis of Water Vapour, some of the ionic products which are produced are as follows: γ + H2O ------> H2O* ------> H2O+ + 2e------->e- + H2O ------>H+ + •OH + 2e- ...

Radiation chemistry is a branch of chemistry which is developed is recent years. Whenever a substance is exposed to extremely high radiations of energy like gamma rays, some reactions take place and these reactions are dealt by Radiation Chemistry. This Process is named as Radiolysis. Radiolysis ...

As we know that any positively charged particle like the alpha particle is positively charged , when approaches the nucleus, it gets repelled by the nucleus. This repulsive force between the approaching positively charged particle and the nucleus is known as the Nuclear Columbic ...
