A method for producing a liquid reaction mixture containing a radioisotope, in particular, a radioactive composition, minimizes device contamination with radioactive substances and increase speed and accuracy with which droplets are mixed. The method for producing a radioactive composition includes placing at least one first droplet Lcontaining a radionuclide and at least one second droplet Lcontaining a labeling substance on at least two respective dimplesamong dimpleson a front surfaceof an insulating layerof a liquid manipulation device, and obtaining a liquid mixture M by using a change in electrostatic force caused by changing voltage applied to the electrodesto thereby cause a relative movement between the at least one first droplet Land the at least one second droplet Lso that the at least one first droplet Land the at least one second droplet Lare mixed together at any one dimple among the dimples
