Archaeological evidence trace practice sth wastf eo e disposal back to antiquity. However, the concept of community-wide systematic collection, treatment, and disposa solif o l d waste wastewated san t evolvno d erdi unti late th le 19th century. The disposal of sewage sludge is a serious problem in many countries due to rapid urbanization Agriculture offers one solution: land application of municipal sewage sludge is practised throughout the world, with beneficial effects on crop yields, soil organic matter, cation exchange capacity, water holding capacit soid yan l fertilit generalym .

Irradiation of any system leads to the formation of highly reactive species, for example hydrated electrons, OH radicals and H atoms in water, which can cause various radiolytic conversions of pollutants: redox reactions, decompositio f organio n c compounds including dyes, formatiof o n precipitates, etc. alss i t o.I well known that ionizing radiatio sterilizina s nha g action.
