Production and Application of Radionuclides
Poster
99mTc is at present, without any doubt, the most extensively used radiotracer in nuclear medicine imaging [1]. Usually, the operation period of research reactors used for the production of 99Mo is about 40-50 years. Most reactors used in the preparation 99Mo have already reached this age, or will reach in the near future. There is a growing interest in exploring cyclotron production of 99mTc...

The generator system Ac-225 / Bi-213 (half life of 45.6 min) is a suitable method of producing an alpha-emitter for targeted alpha thertapy ). However, the production of Ac-225 is difficult and only a limited quantity of this isotope has so far been available for clinical use. Till recently it was exclusively produced by the decay of Th-229, which itself is generated by the decay of U-233...

Non-standard isotopes such as Sc-44/47 and Zr-89 are increasingly finding interest in radiopharmaceutical applications. Methods for the separation of these elements from typical target materials were developed.
The methods are based on the use of extraction chromatographic resins such as UTEVA and DGA resin. Information on the selectivity of the resins (Dw values of selected elements in HCl...

The radionuclides 71As, 72As and 74As have decay properties that are favorable for use in PET investigations, while the heavier isotopes 76As and 77As could potentially be used for tumor therapy. Due to their longer half-lives the compounds labeled with these 5 radionuclides can be used for studying of long-term biological phenomena. Studying antibodies, which usually have a long biological...

In the recent years there has been significant interest in the production of certain isomers, especially the ones with potential applications in the field of nuclear medicine. 117mSn has been considered as an emerging radio therapeutic isotope, which is particularly promising due to its favorable nuclear decay proprieties: T1/2 = 13.60d, 100% IT decay mode and main gamma emission of 159 keV...

With the rising of the global terrorist threat the improvement of the production technology of closed sources potentially able to be used for dirty bomb production becomes more and more important. The risk of radioactive species getting out into the environment can be decreased by embedding those species into insoluble matrices. In this work we would like to report about our research on Cs-137...

Due to its nuclear characteristics, the Auger electron emitter isomer 195mPt (T1/2 = 4.02 d) is a promising radionuclide for radioimmunotherapy. We performed a test experiment to produce the isomer195mPt by double neutron capture by the193Ir target nucleus with consequent population of 195mPt through β− decay, and provided theoretical estimates for the 195mPt yield [1]. One of the advantages...

Samarium-153 is a part of chemicals used for therapy of cancerous growth and inflammatory disease of bone tissue. 153Sm is generated by irradiating 152Sm in either a nuclear reactor or charged-particle accelerator.
A natural mixture of samarium isotopes contains only 26.75% of 152Sm; when irradiated, the specific activity of the generated 153Sm is not enough to use it for the nuclear medicine...

Determining the oxygenation status in tumour hypoxia is a challenge in cancer imaging. There are many ongoing clinical trials using conventional positron emission tomography (PET) scans and PET agents as cellular markers for detection of tumour hypoxia depending on the concept of the basic physics of 2γ annihilation. However, Kacperski and Spyrou (2004) proposed, for the first time, to use 3γ...

Radium-223 is prospective alpha-emmiting therapeutic radionuclide for targeted radionuclide therapy. Although Ra-223 is formed naturally by the decay of U-235, for practical reasons its preparation involves neutron irradiation of Ra-226. The decay of Ra-227 leads to Ac-227, which decays to Th-227 and Ra-223 subsequently. Ra-226 as a decay product of U-238 is generally available in multigram...

The global demand for the rare earth elements has been dramatically enlarged. Therefore, it needs a detailed understanding in ore chemistry and separation methods. To simulate these processes, we will use the radiotracer technique. 135La (T1/2 = 19.4 h) was choosen as a typical representative element (radionuclide) for the rare earth elements. The isotope can be produced by the nuclear...

This theme is the first step to research and develop novel technologies and procedures for recycling and valorisation of historical radiation sources containing Ra-226. Recycling would include their reprocessing to a form suitable for irradiation in a nuclear reactor, production and separation of Ac-227 from Ra-226 and its use for the construction of Ac-227 /Ra-223 radionuclide generator....

Even today the generator-produced radionuclide 99mTc is used for the vast majority of nuclear medical diagnoses. The parent radionuclide 99Mo is generally produced via fission of highly-enriched 235U, however, at a few nuclear reactor sites in the world only. Due to ageing reactors the world supply of fission-produced 99Mo has become somewhat...
