Patent number: 9685249Abstract: Provided is a beta voltaic battery including a first semiconductor layer, a second semiconductor layer, and a beta-ray generator which is disposed between the first semiconductor layer and the second semiconductor layer and includes a metal substrate having both sides coated with a radioisotope layer. The beta voltaic battery according to the present invention has no sealing layer, but may efficiently shield beta rays through a sandwich structure. Since the sealing layer is absent, the absorption of beta rays by the semiconductor may be improved, and excellent energy conversion efficiency may be obtained because output is improved due to the two semiconductor layers and the radioisotope ray source coated on the both sides.Type: GrantFiled: December 21, 2015Date of Patent: June 20, 2017Assignees: KOREA ATOMIC ENERGY RESEARCH INSTITUTE, Electronics and Telecommunications Research InstituteInventors: Young Rang Uhm, Kwang Jae Son, Sung-Weon Kang, Kyung-Hwan Park, Byoung-Gun Choi

Method of preparing iodine seed for treating eye disease or cancer, and iodine seed prepared thereby
Patent number: 9421282Abstract: The present invention provides a technique for adsorbing I-125 on a support for treating cancer and a method of preparing an I-125 seed using the same. Since a method of preparing iodine according to the present invention uses an intermediate having phosphate-based, oxalate-based, or arsenate-based anions introduced thereinto, the intermediate has a substitution effect of iodine 3 to 5 times higher than that of a typically used intermediate having chlorine anions introduced thereinto. According to the substitution effect, control of a radiation dose may be possible during the manufacturing of an iodine seed and an iodine seed may be prepared within a shorter period of time. Also, since an amount of residual radioactive iodine may be decreased as a result of a large amount of adsorption, an amount of radioactive iodine (I-125) waste may be decreased, and the effect thereof may be also high environmentally.Type: GrantFiled: February 12, 2013Date of Patent: August 23, 2016Assignee: Korea Atomic Energy Research InstituteInventors: Kang Hyuk Choi, Kwang Jae Son, Jin-Hee Lee, Sung-Soo Nam, Sun Ju Choi -

Adsorbents for radioisotopes, preparation method thereof, and radioisotope generators using the same
Patent number: 8758714Abstract: Disclosed is a novel adsorbent for use in a 99Mo/99mTc generator, which is a medical diagnostic radioisotope generator, and in a 188W/188Re generator, which is a therapeutic radioisotope generator. The adsorbent composed of sulfated alumina or alumina-sulfated zirconia exhibits adsorption capacity superior to that of conventional adsorbents, and is stable and is thus loaded in a dry state in an adsorption column so that the radioisotope 99Mo or 188W can be adsorbed. Thus, it is possible to miniaturize the column, and such a miniaturized column is small, convenient to use, and highly efficient, and extracts a radioisotope satisfying the requirements for pharmaceuticals, and thus can be useful for radioisotope generators extracting 99mTc or 188Re.Type: GrantFiled: June 7, 2012Date of Patent: June 24, 2014Assignee: Korea Atomic Energy Research InstituteInventors: Jun Sig Lee, Hyon Soo Han, Ul Jae Park, Kwang Jae Son, Hyeon Young Shin, Soon Bog Hong, Kang Duk Jang, Jong Sub Lee -

Publication number: 20080300444Abstract: Disclosed is an ophthalmic applicator for the treatment of pterygium or or glaucoma using a radioisotope. It comprises a source volume for containing the radioisotope therein; a filter volume for controlling a radiation dose emitted from the radioisotope; and an encapsulation volume for encompassing the source volume and the filter volume, wherein the radioisotope is pure 32P or a combination of 32P and 103Pd. Ensuring the formation of more ideal dose distributions than do the conventional 90Sr ophthalmic applicators, as described hitherto, the ophthalmic applicator for the treatment of pterygium or glaucoma using 32P or a combination of 32P and 103Pd can promise both high therapeutic effects on pterygium or glaucoma and high safety effects on the eye lens. Further, 32P and 103Pd are easier to produce and treat than is 90Sr, thereby allowing the radiotherapy to be useful.Type: ApplicationFiled: May 23, 2008Publication date: December 4, 2008Applicants: SEOUL NATIONAL UNIVERSITY HOSPITAL, KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Sung-Joon Ye, IlHan Kim, Won Ryang Wee, Mee Kum Kim, Kwang Jae Son, Hyon Soo Han, Ul Jae Park, Hyeon Young Shin
