Problems solved by technology

This kind of production mode will produce a lot of waste during the operation of the accelerator, and it is highly targeted. Often only one radionuclide mother solution (such as germanium gallium generator, 131I mother solution, 99m Tc mother liquor, etc.) are connected separately, and the equipment utilization rate is low

Abstract

The invention relates to a hot cell for radiopharmaceutical synthesis. The hot cell is divided into a synthesis box body and a product box body by a protective lead clapboard, a synthesis module is arranged in the synthesis box body, a radioactive mother liquor tank and a product tank are arranged in the product box body, the tops of the synthesis box body and the product box body are also provided with air exhaust devices, the synthesis module is placed on a drawing device, and the radioactive mother liquor tank and the product tank are respectively isolated in a lead-shielded lifting device.Compared with like products in the prior art, the hot cell of the invention has the advantages of being flexible in operation, high in safety, convenient to maintain and the like.

Description

technical field [0001] The invention relates to the treatment of radioactively contaminated materials, in particular a hot cell for the synthesis of radiopharmaceuticals. Background technique [0002] Positron radiopharmaceuticals have strong radiation, and the production needs to be operated in a shielded isolation box, which is called a hot cell. Due to the short half-life of positron radionuclides, the general production is fully automatic in dedicated synthesis modules. [0003] At present, the hot chamber of the automatic synthesis module of shielded positron radioactive medicines is generally designed in two parts. Firstly, place the synthesis module shielding hot chamber in the C-level clean area, and there is an air intake and exhaust system in the heat chamber to ensure that the working environment of the synthesis module is C-level. Synthetic products are transferred to the dispensing hot chamber through pipelines for collection and dispensing. A laminar flow pr...
