Abstract

The invention provides a horizontal high-concentration Na<131>I production device, which comprises a dryer, a distillation device, a purifier, an iodine-131 trap, an exhaust gas purifier, a vacuum pump and a controller, wherein the dryer, the distillation device, the purifier, the iodine-131 trap, the exhaust gas purifier and the vacuum pump are sequentially connected through a pipeline; the distillation device, the purifier and the iodine-131 trap are electrically connected with the controller respectively. According to the device, iodine-131 steam distilled from activated TeO2 can be efficiently treated, and about 98 percent of iodine-131 can be recovered to obtain a medical Na<131>I solution at concentration of higher than 10Ci/mL. The device is compact, small and convenient to operate.

Description

Technical field [0001] The invention belongs to the technical field of radioisotope preparation, and specifically relates to a horizontal high-concentration Na 131 I production equipment. Background technique [0002] The main production method of radioactive iodine-131 is the use of distillation from the tellurium dioxide irradiated from the reactor and from the 235 U is extracted from the lobed mixture. Radiopharmaceuticals made of radioactive iodine-131 are widely used in modern nuclear medicine clinical diagnosis and treatment. Sodium iodide (Na 131 I) The radioactive raw materials for medicines and iodine-131-labeled medicines are mainly from tellurium dioxide activated by radiation in the reactor, and are mainly produced by dry distillation. The brief process of dry distillation to produce iodine-131 is: pour the activated tellurium dioxide into a quartz glass container (quartz boat) and put it into the quartz glass tube of the distiller for high-temperature (about 750°C)...
