Studies on radiation treatment of sewage sludge and manure to eliminate the pathogenic bacteria and their use to increase growth of corn at latosol soil have been done at Center for the Application of Isotopes and Radiation (CAIR) since 1984. The parameters measured for irradiated sludge were total bacteria and pathogenic bacteria content, nutrient value, pH, BOD, COD, suspention rate, water content, optimum radiation dose, combined treatment of irradiation and solar energy, packaging materials and storage time after irradiation. Results showed that the combined treatment of solar energy and gamma irradiation could reduce the irradiation dose needed to eliminate the pathogenic bacteria from samples investigated from 6 kGy to 2 kGy in dewatered sludge, and the pH measured were ranging between 6.0 to 7.5. Use of 5 ton/ha of irradiated sludge gave the same effect with those of 90 Kg/ha of TSP on the growth of corn. From nutritional and pH point of view, the irradiated sludge and manure are acceptable to increase soil fertility. This paper is the review of works that have been done and issued at CAIR since 1984
