Evaluation of the low energy cyclotron production of the gamma emitters 107Cd and 109Cd
107Cd (T1/2 = 6.5 h) and 109Cd (T1/2 = 461.9 d) are promising non-standard gamma-emitting radionuclides with significant potential for SPECT use. For the optimized production of the said radionuclides, production routes namely 107Ag(p,n)107Cd, 107Ag(d,2n)107Cd, 109Ag(d,2n)109Cd, 109Ag(p,n)109Cd, 109Ag(p,3n)107Cd and 109Ag(d,4n)107Cd were critically analyzed. The nuclear model codes ALICE-IPPE, TALYS 1.9, and EMPIRE 3.2 were employed to check the consistency and reliability of the experimental data. A validated technique was then used to calculate recommended nuclear cross section values for each production route, considering both experimental data and theoretical modeling. The same approach was followed also for reactions leading to possible radioisotopic impurities. By using the recommended results, thick target yields were then calculated for each production route and corresponding impurity reactions. An optimum energy range for the high purity production with low energy cyclotron was at last suggested.
期刊介绍:
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
