Reaction cross section / Excitation function / nat Te target / Radioisotopes of iodineSummary. The excitation functions of proton induced nuclear reactions on nat Te were measured using the stackedfoil technique up to 14.5 MeV. Samples of thin uniform layers of nat Te on Ti-backing were prepared by electrodeposition. Nuclear reaction cross sections for the formation of 120g,121,123,124,125,126,128,130(m+g) I were determined and their theoretical thick target yields were calculated. The obtained data were compared with the previously published experimental results and the values obtained theoretically using the ALICE-IPPE computer code.

“…Detailed evaluations of the data using nuclear model calculations and statistical fitting procedures have also been performed for several radionuclides [cf . [21][22][23][24]. Thus the nuclear reaction cross section database for the production of innovative positron emitters appears to have considerably improved in recent years.…”

In molecular imaging, the importance of novel longer lived positron emitters, also termed as non-standard or innovative PET radionuclides, has been constantly increasing, especially because they allow studies on slow metabolic processes and in some cases furnish the possibility of quantification of radiation dose in internal radiotherapy. Considerable efforts have been invested worldwide and about 25 positron emitters have been developed. Those efforts relate to interdisciplinary studies dealing with basic nuclear data, high current charged particle irradiation, efficient radiochemical separation and quality control of the desired radionuclide, and recovery of the enriched target material for reuse. In this review all those aspects are briefly discussed, with particular reference to three radionuclides, namely 64 Cu, 124 I and 86 Y, which are presently in great demand. For each radionuclide several nuclear routes were investigated but the ( p, n) reaction on an enriched target isotope was found to be the best for use at a small-sized cyclotron. Some other positron emitting radionuclides, such as 55 Co, 76 Br, 89 Zr, 82m Rb, 94m Tc, 120 I, etc., were also produced via the low-energy ( p, n), ( p, α) or (d, n) reaction. On the other hand, the production of radionuclides 52 Fe, 73 Se, 83 Sr, etc. using intermediate energy ( p, xn) or (d, xn) reactions needs special consideration, the nuclear data and chemical processing methods being of key importance. In a few special cases, a high intensity 3 He-or α-particle beam could be an added advantage. The production of some potentially interesting positron emitters via generator systems, for example 44 Ti/ 44 Sc, 72 Se/ 72 As and 140 Nd/ 140 Pr is considered. The significance of new generation high power accelerators is briefly discussed.

Medical radionuclide / Optimisation of production route / Nuclear reaction cross section / Standardisation of data / Alternative routes for production of 99m Tc and 68 Ga / Non-standard positron emitter / Novel therapeutic radionuclide Summary. Nuclear reaction cross section data are of great significance in optimisation of production routes of radionuclides. This article deals with some newer aspects of data research related to production of both standard and novel radionuclides. The recent work to standardise the known data is discussed and new measurements with regard to further optimisation of production routes of some commonly used radionuclides are mentioned. Attempts to increase the specific activity of some reactor-produced radionuclides through the use of charged-particle induced reactions are outlined. The jeopardy in the supply of 99m Tc via a fission-produced 99 Mo/ 99m Tc generator is considered and its possible direct production at a cyclotron is briefly discussed. Regarding the novel radionuclides, development work is presently focussed on non-standard positron emitters for diagnosis and on low-range highly ionising radiation emitters for internal radiotherapy. Recent nuclear reaction cross section measurements related to the production of the two types of radionuclides are briefly reviewed and some anticipated trends in nuclear data research are considered.
