Everybody was really excited about Curiosity, and that had this big plutonium battery on board that has plutonium-238, which actually has a higher specific activity than the low-enriched uranium fuel of these molten salt reactors, which means that the effects would be negligible, because you lau...
The term “specific activity” is defined as the amount of radioactivity – or the decay rate – of a particular radionuclide per unit mass of the radionuclide. For example, the specific activity of Ra-226 is 1, meaning that one gram of Ra-226 contains one (1) curie (assumed to be uni...
How do we define the concepts specific activity, radioactive concentration, carrier, carrier-free and no-carrier-added?heme oxygenaseoxygen activationbiliverdincoupled oxidationThe fission of highly enriched uranium (HEU) by thermal neutrons creates dozens of isotopic products.

observed in non-mammalian species, including birds and fish. Biochemical analysis revealed that zebrafish brain slices could convert pregnenolone to progesterone, suggesting a 3β-hydroxysteroid dehydrogenase isomerase activity [112]. Another sex hormone, progesterone, could also be important for brain func...
A new process was developed to recover high specific activity (no carrier added)Mo from electron-accelerator irradiated UOor uranyl sulfate targets. The process leverages a novel solvent extraction scheme to recover Mo using di(2-ethylhexyl) phosphoric acid following uranium and transuranics removal ...

Hence, in an industrial site in southern Italy, formerly affected by anthropogenic waste disposal due to the activity of a Pb-battery recycling industrial plant, this work first aimed at tuning a multi-sensor methodology supported by pedological survey (i) to elucidate the spatial variability of ...
