In the shallow land disposal system for radioactive waste arising from research, industrial and medical facilities, effect of environmentally hazardous substances must be considered adding to radiation effect on human. Some environmentally hazardous substances will be regulated following to the Waste Management and Public Cleansing Law, however, boron, fluoride and nitric ion are not regulated by the Waste Management and Public Cleansing Law. Therefore, in this study, the limitation of the amount of boron, fluoride and nitric ion in the waste forms were evaluated in concrete pit and trench facilities.
