    Abstract: PURPOSE:To enable a reduction in the possibility of radiation exposure by introducing a determined amount of radioisotope(RI) solution direct into a diluting vial from a IR generator integrally combined into a device by on-line and measuring its radioactivity. CONSTITUTION:A determined amount of RI solution is sampled into a syringe 32 from a RI generator 30 by the opening and closing of opening and closing valves 36, 37 and the operation of the piston 35 of the syringe 32, then the determined amount of the RI solution is injected into a diluting vial 31. The radioactive strength of this RI solution is measured by a radiation detector. On the other hand, a determined amount of physiological salt solution from a physiological salt solution vessel is sampled into a syringe 40, and then the opening and closing valve 39 is opened to inject the determined amount of the physiological salt solution to the diluting vial 31. Hence, the specific radioactivity can be determined from the amount introduced into the vial 31 and the radioactive strength measured by the radiation detector. As a determined amount of the RI solution can be automatically obtained direct from the RI generator in this way, the possibility of radiation exposure of operators can be reduced.
