Abstract
Man has been consciously modifying hi environment and. using its resources to improve the quality of his life since the earliest civilizations. The industrial revolution, however, arose a new problem of pollution. Growing exploitation and processing of environmental resources of all kinds, the presence of biological effects of many chemical residues, such as those of pesticides, industrial solvents fossil-fuel combustion products besides the radioactive waste which are at low concentrations and quite undetectable by the senses. During their lifetimes human and other animal us well as plant organ! IUS are exposed not to one but to several contaminant, either simultaneously or consecutively. For environmental safety, different operations are required to control side effect of human activities that produce several hundreds of contaminant The radioactive pollution i indeed greatly harmful and represents one of the most dangerous hazards that would seriously affect the living environment This is due to the fact that waste effluents from nuclear activities generally contain trace to minor quantities of radionuclides and would represent variable radiation levels. Release of these effluents to environment represents radiation hazards for man and his environment. Decontamination of these waste effluents from radioactive materials to acceptable levels is thus of major importance. Such decontamination is indeed of vital importance as some of these substances eventually enter the body either by inhalation (via the air that is breathed) or by ingestion of contaminated food stuffs and drink or direct adsorption through skin.
