Three years later, measurements were repeated for four workers with the highest concentrations of uranium in urine. The results of site-specific measurements of dose rates, long-lived alpha-particle activity concentrations and equivalent equilibrium volume activity of radon were derived from the archive...

that can rapidly recover microcurie quantities of99Mo from irradiated uranium targets. The discussion will focus on the chemistry surrounding UREX, MoLLE, and the concentration column in order to achieve high purity, high specific activity99Mo. Potential improvements to this process are also discussed...
Moreover, upregulation of Ndufs1 expression improved the reduced activity of complex I and impaired mitochondrial respiratory function caused by MI/hypoxia. Given that mitochondrial function and cardiomyocyte apoptosis are closely related to heart failure after MI, the results of this study suggest ...
of the telencephalic area, periventricular nucleus of the posterior tuberculum and the ventral part of the periventricular pretectal nucleus. In males, the dorsal zone of the periventricular hypothalamus showed higher activity [94]. The adult neurogenesis capability dictates neural plasticity; it has ...
Since DU has a low specific activity in comparison to natural uranium, it is not considered to be a significant radiological hazard. The potential contribution of radiation to DU-induced biological effects is unknown, and the involvement of radiation in DU-induced biological effects could have ...

The specific alpha activity of U-234 was determined using pure samples grown from UX. The half-life was found to be 2.67 +- 0.04 (L.E.) x 10 exp 5 yr. The corresponding weight fraction in natural uranium was found to be 0.0000584 +- 0.0000008. 4 tabs. (ERA citation 11:008024)...
The [Ba+Fe]-coprecipitation method is applied to measure gross alpha activity for radiological examination of drinking water in the laboratory. This method collects all the alpha-emitting radionuclides of interest (natural alpha emitters and transuranium elements) in a precipitate on a filter. This...
α particles must be monitored to be managed as radioactive diagnostic agents or nuclear activity indicators. The new generation of perovskite detectors suffer from limited energy resolution, which affects spectroscopy and imaging applications. Here, we report that the solution-grown CsPbBr3crystal exhibi...
