Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 , figure 2 As shown, the xenon gas target used for the production of iodine-125 by reactor irradiation includes a cylinder 1, a sealing cap 2 and a protective cap 3. The upper part of the cylinder 1 and the lower end of the sealing cap 2 are welded by argon arc, and the upper end of the sealing cap 2 is provided with There is an air inlet 4, and xenon gas is poured into the cylinder 1 through the air inlet 4; the air inlet 4 is sealed by cold welding, and the sealing cap 2 is covered with a protective cap 3.

[0019] The cylinder body 1 is made of pure aluminum; the volume of the cylinder body 1 is 50-150ml, and in this embodiment, it is 100ml.

[0020] The sealing cap 2 is made of pure aluminum.

[0021] The protective cap 3 is made of pure aluminum.

Abstract

The invention discloses a Xenon target for producing iodine-125 through reactor irradiation and a preparation method thereof. The Xenon target comprises a barrel body, a sealing cap and a protection cap, wherein the upper part of the barrel body and the lower end of the sealing cap are subjected to argonarc welding, an air inlet is arranged at the upper end of the sealing cap, and Xenon is injected to the barrel body through the air inlet; and the air let is subjected to cold-welding sealing, and the protection cover covers the sealing cap. The target prepared by the invention by adopting a cold welding method is simple and convenient for operation, easy to control the charge quantity of target materials, and stable and reliable in performance in the process for producing iodine-125 through reactor irradiation, and has high pressure resistance.

Description

Technical field [0001] The invention relates to a xenon gas target, in particular to a xenon gas target used for the production of iodine-125 by reactor irradiation and a preparation method thereof. Background technique [0002] At present, iodine-125 is mainly used for in vitro radioimmunoassay and preparation of iodine-125 seed sources. Its preparation method is generally to use natural xenon or enriched xenon ( 124 Xe) via nuclear reaction The irradiation method includes a circulating loop method and a batch irradiation method. The loop method is to use enrichment 124 Xe is irradiated cyclically in the reactor, which requires a large investment and complicated equipment; the batch irradiation method has a small investment and simple equipment. Generates iodine-125. The key of batch irradiation method lies in the preparation of irradiation target and the selection of irradiation conditions. At present, there is no document that discloses the structure and preparatio...
