Problems solved by technology

However, the disadvantage of this production method is that the cost of equipment and production is higher than any other production method
Although this production method has the advantage of being able to obtain highly pure and highly radioactive iodine-125, it has the disadvantage that the equipment and production costs are as high as the aforementioned loop production

Abstract

The invention provides an inner circulation irradiation box which can be used to produce iodine-125 and a related production method. An irradiation box filled with xenon gas has a lower irradiation section and an upper irradiation section, and a neutron control member. The lower irradiation part is inserted into the irradiation hole of the reactor core and directly irradiated with a large amount of neutrons. Iodine-125 is produced from xenon gas when neutrons are irradiated to xenon gas. The upper irradiated portion protrudes from the irradiated hole, and iodine-125 is transported to the upper irradiated portion by convection and cured in the upper portion. The neutron control component reduces neutrons in the upper section to mass produce highly pure and highly radioactive iodine-125.

Description

technical field [0001] This application generally relates to the production of iodine-125 ( 125 I) The equipment and method, especially relate to the inner circulation irradiation box and related manufacturing method that can be used to produce iodine-125 as medical radioisotope. Background technique [0002] In recent years, iodine radionuclides have been produced in small quantities using accelerators or cyclotrons only for research purposes. In 1938, radioactive iodine was further used in the study of the physiological function of the thyroid gland and has been used in tumor treatment. After that, radioactive iodine was widely used in radiopharmaceuticals. [0003] Since halogen elements can be easily substituted in almost all organic compounds, and can have high yield and product stability, they can be widely used in the synthesis of markers. Iodine is a typical one. Iodine radionuclides include iodine-123 ( 123 I), iodine-124 ( 124 I), iodine-125 ( 125 I), iodine...
