The mechanisms by which Pu(IV) is oxidized in aquatic environments is not entirely clear. At Oak Ridge, laboratory experiments have shown that oxidation occurs when small volumes of unhydrolyzed Pu(IV) species (i.e., Pu(IV) in strong acid solution as a citric acid complex or in 45 percent Na2Coj) are added to large volumes of neutral-to-alkaline solutions(23). In repeated experiments, the ratios of oxidized to reduced species were not reproducible after dilution/hydrolysis, nor did the ratios of the oxidation states come to any equilibrium concentrations after two months of observation. These results indicate that rapid oxidation probably occurs at some step in the hydrolysis of reduced plutonium, but that this oxidation was not experimentally controllable. The subsequent failure of the various experimental solutions to converge to similar high ratios of Pu(V+VI)/Pu(III+IV) demonstrated that the rate of oxidation is extremely slow after Pu(IV) hydrolysis reactions are complete.

None of the discoveries —from Italy, Illinois, or Ohio—could be confirmed by other scientists. A great debate went on for many years as to whether element 61 had really been found or not. Finally, the problem was solved. During World War II (1939—1945), scientists at the Oak Ridge Laboratory in Oak Ridge, Tennessee, were studying the materials formed during atomic fission. Atomic fission is the process in which large...

Both the Frankline Institute [2] and the Oak Ridge Laboratory [2] in the USA made a start on the research and development required for the Fort St. Vram high-temperature gas-cooled reactor. The choice was made of a cylinder with flat top and bottom caps. Both in the wall and in the cap the prestressing was by means of cables of variable curvature. 

The example of the Oak Ridge Laboratory poster on which an operator pays his respects to a radioactive source in a zone with a Radiation, Danger, Keep away sign illustrated with two sentences Radiation need to be feared. .. but it must command your respect , directly shows injunction as a flux. Indeed, Radiation need to be feared is a general message. One must be afraid of radiations as they have an impact on health. One should not...
