    Thereafter, Silkwood and two other co-workers personally associated with her (roommate Sherri Ellis and boyfriend Drew Stephens) would be tested at Los Alamos National Laboratory; while the latter two only tested positive for insignificant amounts of plutonium exposure, Silkwood was found to have 6–7 nanocuries (220–260 Bq) of plutonium-239 ...

    The odd numbered fissile plutonium isotopes present in spent nuclear fuel, such as Pu-239, decrease significantly as a percentage of the total composition of all plutonium isotopes (which was 1.11% in the first example above) as higher and higher burnups take place, while the even numbered non-fissile plutonium isotopes (e.g. Pu-238, Pu-240 and ...

    The plutonium, dissolved in an organic solvent, flowed into the center of the vortex. Due to a procedural error, the mixture contained 3.27 kg of plutonium, which reached criticality for about 200 microseconds. Kelley received 3,900 to 4,900 rad (36.385 to 45.715 Sv) according to later estimates.

    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.
