In this paper, risk assessment was conducted to verify self - disposal requirements by landfill for exempted incineration ash by using Resrad Ver.6.5 computer code. The result of risk assessment by landfill for the incineration by-product is that individual dose is 6.91×10-2 μSv y-1 and collective dose is 3.475×10-7 man-Sv y-1. It proved that the result meets reference dose of individual dose 10 μSv y-1 and collective dose 1 man-Sv y-1 for general public. According to the current ‘Nuclear Safety Commission Notice [No. 2014-3]’, it states that the exempted wastes can be disposed of by incineration, landfill and recycling. However, most of recently documents and papers related to exempted wastes are disposed of by landfill and recyling and it could not confirm the case of exempt by incineration. If the national consensus is derived and treating the waste by using process of incineration is activated, it could be considered to treat low level of radiation wastewater and activated carbon excluded from exempted waste because of nuclide 3H and 14C.
