Introduction To Gamma Irradiation
Ionizing radiation has high energy which is enough to break the molecular bonds and ionize atoms. As a result, materials exposed to this radiation undergo modification in their physical, chemical and biological properties. At present, the principal industrial applications of this radiation are sterilization of health care products including pharmaceuticals, irradiation of food and agriculture products (for various end objectives, such as dis-infestation, shelf life extension, sprout inhibition, pest control and sterilization etc.) and materials modification (such as chain scission, polymer cross linking and gemstone colorization etc.) A significant impetus was given to the radiation processing industry with the advent of nuclear reactors, which have the capability to produce radioisotopes.
