Na 125 I solution production device

Abstract

The invention provides a Na 125 I solution production device. The device comprises a rack, a gas pouring tank, a targeting unit, a filling welding unit, a reactor, a raw material tank, a vacuum pump, a pressure gauge and a liquid nitrogen pump. The gas pouring tank, the targeting unit, the filling welding unit, the reactor, the raw material tank and the vacuum pump are all arranged on the rack and fixedly connected with the rack. The pressure gauge is connected with the gas pouring tank. The liquid nitrogen pump is connected with the targeting unit, the filling welding unit, the reactor and the raw material tank respectively. The device is provided with functions of targeting, target production, activation xenon cooling decay, Na 125 I solution concentration and the like, capable of producing high-concentration Na 125 I solutions and producing xenon recovered on line into targets to be reused, compact and small and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of radioisotope preparation, in particular to a Na 125 I solution production device. Background technique [0002] Seed sources, radioimmune drugs and isotope tracers made of radioactive iodine-125 are widely used in modern nuclear medicine clinical diagnosis and treatment, oil logging and other fields, which mainly use reactor irradiation 124 Xe production. At present, sodium iodide (Na 125 I) The solution mainly uses independent targets (concentrated 124 Xe target) irradiation production method, the brief process of the production is: the concentrated 124 Xe gas is injected into a quartz glass container or a metal container and sealed, placed in the reactor for 1-3 days of irradiation, the target is taken out and opened in a hot chamber, the irradiated xenon is transferred into a clean container, sealed and cooled for about 2 weeks, and then the xenon is irradiated recovery, and then add an appropri...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the Na in the prior art 125 The operating sites of the target making, target opening, xenon gas pouring, storage and cooling, distillation and concentration of the I solution production device are scattered and require a large operating space. There are many links for transferring radioactive materials between different processing sites, and the work efficiency is low. , the leakage of the target material is relatively large, and it is easy to cause radioactive contamination of the target device, personnel and the environment. The present invention provides a Na 125 I solution production device
