<P>PROBLEM TO BE SOLVED: To provide a dispensing method and apparatus capable of precisely dispensing a radioactive liquid by using a syringe. <P>SOLUTION: By using the syringe 26 provided with a cylinder 30 and a piston 32 sliding in the cylinder 30, the radioactive liquid of 0.2 cc is dispensed. First, the piston 32 is pulled up to 0.5 cc to draw the radioactive liquid into the syringe 26 through a first tube 48. Next, the piston 32 is pushed back to 0.2 cc to return the not required part of the radioactive liquid in the syringe 26 through the first tube 48. Then, communication between the syringe 26 and the first tube 48 is cut off, the syringe 26 and a second tube 52 are communicated with each other, and the piston 32 is pushed back to 0 cc being an initial position to discharge the radioactive liquid through the second tube 52. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
