“…These studies usually combine NDT and destructive testing methods, for example, LM and SEM observation of metallographic samples, particle-induced X-ray emission (PIXE) analysis, inductively coupled plasma (ICP) analysis, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) analysis [ 19 , 22 , 23 , 27 , 28 ]. Some possible NDT methods that can be applied for elemental bulk analysis of silver coins are the neutron activation analysis (NAA) and the prompt-gamma activation analysis (PGAA) [ 34 , 35 , 36 , 37 , 38 , 39 ]. Yet these methods have some limitations resulting from the high cross section for neutron capture by silver itself, and therefore the silver data would prevent revealing trace elements that could be useful fingerprint variations in the minting process.…”

Silver coins were the first coins to be manufactured by mass production in the southern Levant. An assemblage of tiny provincial silver coins of the local (Judahite standard) and (Attic) obol-based denominations from the Persian and Hellenistic period Yehud and dated to the second half of the fourth century BCE were analyzed to determine their material composition. Of the 50 silver coins, 32 are defined as Type 5 (Athena/Owl) of the Persian period Yehud series (ca. 350–333 BCE); 9 are Type 16 (Persian king wearing a jagged crown/Falcon in flight) (ca. 350–333); 3 are Type 24 series (Portrait/Falcon) of the Macedonian period (ca. 333–306 BCE); and 6 are Type 31 (Portrait/Falcon) (ca. 306–302/1 BCE). The coins underwent visual testing, multi-focal light microscope observation, XRF analysis, and SEM-EDS analysis. The metallurgical findings revealed that all the coins from the Type 5, 16, 24, and 31 series are made of high-purity silver with a small percentage of copper. Based on these results, it is suggested that each series was manufactured using a controlled composition of silver–copper alloy. The findings present novel information about the material culture of the southern Levant during the Late Persian period and Macedonian period, as expressed through the production and use of these silver coins.

“… Goldman et al (1966) performed Tl determination using X-ray emission spectroscopy in urine and feces at ppm levels. Neutron activation analysis (NAA) is another nondestructive analytical technique for trace element determination with an ultralow detection limit and simple preparation of samples ( Das et al, 2023 ). Minoia et al (1990) used NAA to perform Tl determination in urine and blood from healthy Italians.…”

“…During the middle of the 20th century, particle accelerators and high-resolution detectors accelerated the development of nuclear analysis techniques (Calligaro et al, 2022) (Hussein et al, 2019). Neutron activation analysis (NAA), gamma-ray spectroscopy, and X-ray fluorescence have gained popularity due to their ability to detect trace concentrations of elements in a variety of samples (El-Taher, 2018) (Das et al, 2023). These techniques were utilized in environmental monitoring, archaeology, forensics, and industrial quality assurance(Meier-Augenstein, 2011) (Cox & Hunter, 2005).…”

This research investigates radiochemistry and nuclear analysis technologies to make applications safer and more sustainable. A mathematical optimization approach optimizes radiopharmaceutical synthesis parameters for positron emission tomography (PET) imaging to maximize yield and minimize radioactive waste. Optimizing critical parameters improves the efficiency, safety, and sustainability of radiochemistry and nuclear technologies in medical imaging, nuclear energy, and environmental monitoring. The numerical example shows that optimization achieves the study goal. Optimization strategies improve medical imaging by increasing radiopharmaceutical yield and decreasing radioactive waste volume. Real-world implementation requires cost-effectiveness, safety restrictions, and numerous synthesis factors. Researchers, policymakers, and industry professionals must collaborate to enhance human and environmental welfare, according to the report. In conclusion, this research advances radiochemistry and nuclear procedures for safer and more sustainable applications, mitigating hazards and environmental effect and ensuring a safer and more sustainable future for nuclear technology.
