Investigation of the production routes of Palladium-103 and Iodine-125 radioisotopes
Radiation Physics and Chemistry, 2022The most commonly used radioisotopes are Palladium-103 (103Pd) and Iodine-125 (125I) for interstitial application in brachytherapy. In the present study, different production routes of 103Pd and 125I have been investigated. The different level density and optical models of the TALYS 1.95 have been used to determine 103Rh(p,n)103Pd, 103Rh(d,2n)103Pd ...

The Radiopharmaceutical Chemistry of the Radioisotopes of Iodine
Radiopharmaceutical Chemistry, 2019Radioisotopes of iodine have been incorporated into a wide variety of radiopharmaceuticals ranging from small, low molecular weight compounds to large molecules like antibodies. Because of the routine availability of radioisotopes of iodine with different nuclear decay properties, radioiodination is an attractive strategy because the same chemistry can

Microbial Transformation of Iodine: From Radioisotopes to Iodine Deficiency.
Advances in Applied Microbiology, 2017Iodine is a biophilic element that is important for human health, both as an essential component of several thyroid hormones and, on the other hand, as a potential carcinogen in the form of radioiodine generated by anthropogenic nuclear activity. Iodine exists in multiple oxidation states (-1, 0, +1, +3, +5, and +7), primarily as molecular iodine (I2),

The Sorption of Technetium and Iodine Radioisotopes by Various Minerals
Nuclear Technology, 1978Radioisotopes of technetium and iodine, elements that are present in reactor wastes, are strongly sorbed (100 ≲ KD ≲ 2000) from aqueous solutions by several naturally occurring minerals (bournonite, chalcopyrite, pyrite, tennantite, and tetrahedrite ...

Radioisotopes of iodine and xenon of masses 120 and 121
Journal of Inorganic and Nuclear Chemistry, 1965 Abstract A new 43 ± 3 min 120 Xe has been produced by spallation of I with 340 MeV protons. New values for the half-lives of 120 I, 121 Xe and 121 I have been determined. Positron and gamma ray energies have been measured.

Abstract The negatively charged surface of chabazite reduces its efficiency for the sorption of anionic species of radionuclides due to the repulsion force between the anionic species and the negative charge of chabazite surface. Therefore, this work focused on the modification of chabazite using N-methylene aniline to produce Ch-NMA composite for ...

Production and Clinical Development of a New Ideal Radioisotope of Iodine — Iodine-123
, 1971 The use of radioiodine for thyroid tests still comprises some 57 % of the proce-dures performed in Nuclear Medicine Laboratories according to the recent Stanford Research Institute Survey conducted by the Bureau for Radiological Health [1]. Wide diagnostic use of Iodine-131 for thyroid tests results in what has been considered a tolerable absorbed ...

Rapid synthesis of Pb5(VO4)3I, a potential immobilisation host for iodine radioisotopes, was achieved in an open container by microwave dielectric heating of a mixture of PbO, PbI2, and V2O5 at a power of 800 W for 180 s (at 2.45 GHz). The resulting ceramic bodies exhibited a zoned microstructure, differentiated by inter-granular porosity and phase ...

Purification of recovered tellurium dioxide for re-use in iodine radioisotope production
Applied Radiation and Isotopes, 2001 In the production of radioiodine via charged particle activation of isotopically enriched TeO2 and subsequent heating of the irradiated target, some TeO2 is lost. Again, use of recovered TeO2 for radioiodine production showed that impurities are present, which prevent complete volatilization of radioiodine from the heated target.
