Production of <sup>230</sup>Pa as a Source for Medical Radionuclides <sup>230</sup>U and <sup>226</sup>Th Including Isolation by Liquid–liquid Extraction
نویسندگان
چکیده
The experimental cross sections of Pa-230 formation in the reaction 232Th(p,3n)230Pa for protons energy range 140-35 MeV are determined and compared with literature data. yield U-230 impurities U-232 U-233 depending on entering a thick thorium target estimated. Liquid-liquid extraction 1-octanol solution addition Al(III) as masking agent followed by back-extraction 7M HNO3+0.01M HF allows selective Pa isolation from irradiated Th proposes simultaneous production medical Ac-225 Pa-230/U-230 same Th-target.

Advantages of Placenta as a Source for Mass Production of HLA-Antisera
Human Leukocyte Antigens (HLA) of fetus are responsible for induction of HLA antibodies in mother. Exposure to the mismatched paternal HLA antigens in the fetus gives rise to a polyclonal antibody response against paternal HLA antigens. HLA antibodies are present in the maternal circulation of the placenta and are absorbed onto the placenta [1]. The major source of HLA antisera is from sera of ...
