PROBLEM TO BE SOLVED: To provide a target for manufacturing a radioisotope raising the manufacturing efficiency of the radioisotope by restraining the target from being spattered by accelerated particles and efficiently cooling a target material. SOLUTION: The target 3 comprises a target body 31 having a storage section 34 for storing target water as the target material and a target coating 32 coating the surface of the storage section 34. The sputtering yield of the target coating 32 due to the accelerated particles is smaller than the sputtering yield of the target body 31 due to the accelerated particles. The thermal conductivity of the target body 31 is larger than that of the target coating 32. COPYRIGHT: (C)2006,JPO&NCIPI
