Laws and regulations of radioactive waste management related to the Exemption system and the Clearance systembetween governing authorities in Korea and Japan were investigated to suggest better management of radioactive waste.Above both system, very low levels of radioactive wastes which have negligible risk can be decided on being Exclusionsystem and classified as a non-radioactive waste. As a result, the Exemption systems between two countries were similar,whereas the Clearance systems were different. With regard to laws related to the Clearance, Japan specify providinginformation and feedback among relevant authorities, but there is no specification in Korea. In addition, this study suggeststo develop accredited analysis methods to improve the accuracy and reproducibility of the measurement, because twocountries have not established the national accredited analysis method for determining the concentration of radionuclide.
