Problems solved by technology

[0009] However, in conventional targets, since the storage recess is defined by one flat bottom surface and four flat side surfaces, when the pressure inside the storage recess is increased, stress tends to concentrate on the corners of the storage recess.
Therefore, in conventional targets, there is a limit to making the housing recess in a thin-walled shell shape and increasing the pressure inside the housing recess, and it is difficult to sufficiently suppress the boiling of the target liquid.

no. 2 Embodiment approach

[0086] (2.1) Structure of radioisotope manufacturing facility

[0087] Next, refer to Figure 7 ~ Figure 13 The configuration of the radioisotope manufacturing apparatus 2 according to the second embodiment will be described focusing on differences from the radioisotope manufacturing apparatus 1 according to the first embodiment.

[0088] like Figure 7 ~ Figure 11 As shown, the target 20 has a thin-walled shell-shaped portion 20a and an annular support portion 20b that supports the thin-walled shell-shaped portion 20a so as to surround the periphery of the thin-walled shell-shaped portion 20a. Therefore, in the target 20, the space surrounded by the thin-walled shell-shaped portion 20a and the annular support portion 20b constitutes a storage recess 40 for storing the target liquid L on the front end surface 36 side, and a housing recess 40 for storing the target liquid L is formed on the base end surface 38 side. 3 The fitting recess 42 of the body part 22. In addition, i...

Abstract

Boiling of a target liquid is suppressed sufficiently by enhancing both pressure tightness of a target and cooling effect of the target liquid. The radioisotope production system includes a cyclotronfor irradiating radiation, and a target (20) having a recess (40) for containing a target liquid L. The containing recess (40) includes an opening (44) for introducing radiation irradiated from the cyclotron, and a spherical bottom surface (48) recessed toward the direction receding from the opening (44) to have a top (58). The target (20) is arranged such that the intersection of the irradiationaxis X of radiation from the cyclotron and the bottom surface (48) is located directly under the top (58).

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2007-153077 filed on June 8, 2007. The entire content of this application is incorporated in this specification by reference. [0002] The present invention relates to a radioisotope production device and a radioisotope production method for producing a radioisotope through a nuclear reaction between a target liquid and radiation. Background technique [0003] Positron Emission Tomography (PET: Positron Emission Tomography) is used as an inspection method for precise inspection of brain, heart, cancer, and the like. In this PET examination, an examination drug labeled with a radioactive isotope (positron-emitting atomic nuclide) that emits positrons (positrons) is introduced into the subject by injection or inhalation. The test agent introduced into the body is metabolized or accumulated in a specific site (for example, tumor or lesion site). Radiation (annihilation gamma ray)...
