The biosphere has important function in the safety assessment of a radioactive wastedisposal facility. A biosphere model in the safety assessment needs various input data that containsignificantly inherent uncertainties. This paper reviews the effects of the input data on the radiologicalimpact assessment from main radionuclides such as 14C and 99Tc in the biosphere model. In addition, itis confirmed that the safety criteria is met, when the conservative input data for the intake rate, soil toplant concentration ratio, and distribution coefficients of the radionuclides are applied and probabilisticanalysis are conducted in the biosphere model. Nevertheless, it is required to generate site-specific inputdata for the confidence building and reduce excessive conservatism in the biosphere model.
