The relationship between the fraction leached and the ratio of surface area and volume (<I>S/V</I>) of a specimen has been studied in order to evaluate the safety of a cement composite for disposal. The leaching fraction of radionuclides was measured for the different <I>S/V</I> ratios. In a case of either <SUP>137</SUP>Cs, <SUP>90</SUP>Sr or <SUP>60</SUP>Co, the amount leached is directly proportional to the <I>S/V</I> ratio. It is in harmony with the empirical formula proposed here, which can be derived from the diffusion equation with a semi-infinite plane source model.<BR>The amounts of <SUP>137</SUP>Cs, <SUP>90</SUP>Sr and <SUP>60</SUP>Co leached from a cement composite of 2001 drum size are estimated on the basis of the above relation, referring to the data obtained with a cylindrical shape specimen (4. 5 cm in dia. and 4. 4 cm high)
