Pu-239 is a 2006 British drama film written and directed by Hollywood producer Scott Z. Burns in his feature directorial debut, which was based on the book PU-239 and Other Russian Fantasies written by Ken Kalfus.
In February 1940, Glenn Seaborg and Edwin McMillan produced plutonium-239 by bombarding uranium with deuterons. This produced neptunium, element 93, which underwent beta-decay to form a new element, plutonium, with 94 protons. [4] Kennedy built a series of detectors and counters to verify the presence of plutonium.
Fissioning of plutonium-239 provides more than one-third of the total energy produced in a typical commercial nuclear power plant. [6] Reactor fuel would accumulate much more than 0.8% plutonium-239 during its service life if some plutonium-239 were not constantly being "burned off" by fissioning. A small percentage of plutonium-239 can be ...
Had all of the plutonium given to Stevens been the long-lived Pu-239 as used in similar experiments of the time, Stevens's lifetime dose would have been significantly smaller. The short half-life of 87.7 years of Pu-238 means that a large amount of it decayed during its time inside his body, especially when compared to the 24,100 year half-life ...
Plutonium-239 (239 Pu) makes effective weapons material, although it requires an implosion-type mechanism rather than the simpler gun-type trigger used in the Thin Man uranium bomb. Heavy water has been demonstrated as an effective moderator for 239 Pu production, and may be separated from ordinary water by electrolysis.
Seaborg's role was to figure out how to extract the tiny bit of plutonium from the mass of uranium. Plutonium-239 was isolated in visible amounts using a transmutation reaction on August 20, 1942, and weighed on September 10, 1942, in Seaborg's Chicago laboratory. He was responsible for the multi-stage chemical process that separated ...
One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.
