METHOD FOR SYNTHESIZING RADIOACTIVE TECHNETIUM-99M-CONTAINING SUBSTANCE AND SYNTHESIZING DEVICE

摘要

A method for synthesizing a radioactive technetium-99m-containing substance and a synthesizing device are provided. The method for synthesizing a radioactive technetium-99m-containing substance has a step for generating negative muons and a step for irradiating the negative muons onto a ruthenium sample. The ruthenium material preferably includes a metallic ruthenium and/or a ruthenium compound. Also, the ruthenium sample preferably has a plurality of superimposed ruthenium thin plates having a thickness of 4 mm or less.
