“…The ( , ) process has been extensively investigated, but all the measurements have generally been done at 0.0253 eV, i.e. integral measurements over the region of thermal energies [1][2][3][4][5][6][7][8][9]. In the thermal region, the cross section follows the wellknown 1/v law of neutron capture, but the point of normalization is the value at 0.0253 eV.…”

Measurement of cross section of the98 Mo(n, ) 99 Mo reaction using monochromatic thermal neutrons Abstract: The cross sections of the reaction 98 Mo( , ) 99 Mo at neutron energies of 0.0334 eV and 0.0536 eV were measured for the first time using the activation technique, and the resulting values of 116 ± 7 mb and 91 ± 5 mb, respectively, are in good agreement with the JENDL-4 and ENDF/B-VII data files. Those measured values were extrapolated to the energy 0.0253 eV assuming 1/v dependence in the thermal region and the results were compared with the integrally measured values reported in the literature. The new data are thus useful to check the evaluated excitation function.

“…The detection efficiency for the γ -ray spectrometer was calibrated with an IAEA mixed standard radionuclide solution containing 60 Co, 241 Am, 109 Cd, 54 Mn, 65 Zn, 85 Sr, 203 Hg, and 57 Co. The measured detection efficiencies were fitted by the polynomial function in equation ( 2 ) (Osae et al 1999 ; Van Do et al 2009 ). As a way of reducing uncertainties caused by pile-up effects and random coincidence, the sample-to-detector distance was kept and maintained at 7.2 cm from the top of the detector surface during measurement.…”

Instrumental neutron activation analysis using the single-comparator method has been used for the multielement determination of essential elements in two main types of Pito brewed locally in Ghana. The precision and accuracy of the analytical method was validated and found to be within 10%. In all, eight different brands of Pito depending on the type of cereal crop used in brewing were analyzed for 13 different elements (Al, As, Ba, Cl, Co, Cu, Fe, K, Mg, Mn, Na, Si, and Zn). It was observed that all brands were particularly enriched in nutrient elements Cl, Mg, and K. The rest were generally found in varying concentrations. As these elements are bioavailable in natural form, perhaps in combination with organic constituents, they are likely to be easily digested and assimilated by the human body. Arsenic, a toxic element, was found in insignificant amounts suggesting that it was within safe limits.

“…98 Mo used to produce 99 Mo by the (n,γ) reaction was proposed as a promising solution, which has inspired further development, with the advantages of radioactive waste, cost reduction, and non-proliferation [10]. The neutron activation of 98 Mo by the reaction ( 98 Mo(n,γ) 99 Mo) has a small activation cross-section (0.13 b for thermal neutrons) compared with the neutron fission production of 99 Mo (584 b for thermal neutrons) [11]. From this perspective, it is required to increase the yield of 99 Mo, and a variety of research has been carried out towards this objective (e.g., increasing the enrichment of 98 Mo, and increasing the density of the pellet) [12,13].…”

Technetium-99m(99mTc) is used worldwide in 85% of nuclear medicine diagnostic imaging procedures. We developed porous MoO2 pellets as an alternative to reactor-based targets in an (n,γ) reaction for producing Technetium-99m (99mTc) in nuclear medicine. The pellets, formed through a manufacturing process involving mixing, sintering, eluting, and drying, offer advantages such as selective dissolution and improved yield. This research offers a potential solution for stable 99mTc production, focusing on porous molybdenum dioxide (MoO2) as a target material due to its insolubility in water. Using potassium molybdate (K2MoO4) as a pore former, we developed porous MoO2 pellets that facilitate efficient technetium extraction and target recycling. This approach offers control over pore formation and shows promise in addressing supply challenges and enhancing 99mTc production.
