Shielding design and heat transfer analysis of the transportation container of a hot batch in the Mo production facility.

In molybdenum-99 (Mo) production facilities via the fission method, appropriate transportation containers must be used to transfer irradiated targets from the irradiation facility to the processing facility, following the requirements for transferring radioactive materials. In the Mo production industrial plan of Iran, the transportation container must be capable of carrying a holster containing nine irradiated low-enriched uranium targets, known as a hot batch. In this article, the proper shielding of two-layer containers based on the gamma spectrum emitted from the radioisotope inventory of a local hot batch, including fission products, activation products, and other radioisotopes produced from their decay chains, was investigated by using Monte Carlo code MCNP6.

Uranium poisoning, particularly from exposure to Depleted Uranium (DU), occurs when uranyl ions enter the bloodstream and bind primarily to transferrin, osteopontin, and albumin before entering cells via corresponding receptors on renal tubular membranes, leading to cellular damage. Uranium poisoning remains a significant clinical challenge, with no ideal treatment currently available. In this study, we investigate the therapeutic potential of human umbilical cord-derived mesenchymal stem cell exosomes (MSC-EXs) in mice exposed to DU.

- The study investigates uranium (U/U) ratios in environmental samples from the Pamir region to evaluate the influence of human nuclear activity on this remote area.
- The U/U ratios found (ranging from 0.007256 to 0.007263) suggest a slight enrichment of uranium, indicating the presence of anthropogenic materials, particularly in cryoconite compared to soil and water.
- The findings also suggest that while the area shows subtle enrichment of uranium, it remains relatively clean from local contamination, with environmental uranium largely resulting from historical global nuclear fallout rather than local sources.
Mitigation of depleted uranium-induced mitochondrial damage by ethylmalonic encephalopathy 1 protein via modulation of hydrogen sulfide and glutathione pathways.

Depleted uranium (DU) is a byproduct of uranium enrichment, which can cause heavy-metal toxicity and radiation toxicity as well as serious damage to the kidneys. However, the mechanism of renal injury induced by DU is still unclear. This study aimed to explore the role of ethylmalonic encephalopathy 1 (ETHE1) in DU-induced mitochondrial dysfunction and elucidate the underlying mechanisms.

With the depletion of fossil fuels and increasing pollution problems, green and sustainable energy supply attracts worldwide attention. Hydrogen is a green and high-density energy substance, and photocatalytic hydrogen generation is an effective and sustainable method. Therefore, developing high-performance photocatalysts plays a crucial role in practical application.
