These changes can be detected by blood tests after receiving a whole-body acute dose as low as 0.25 grays (25 rad), though they might never be felt by the patient if the dose is below 1 gray (100 rad). Conventional trauma and burns resulting from a bomb blast are complicated by the poor wound healing caused by hematopoietic syndrome, increasing ...
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 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.
Fat Man, the nuclear bomb that was detonated over Nagasaki, Japan on August 9, 1945, also contained Hanford's plutonium. The bomb killed an estimated 50,000 people in Nagasaki, The BBC reported.
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
Measures such as "LD 1" and "LD 99" (dosage required to kill 1% or 99%, respectively, of the test population) are occasionally used for specific purposes. [ 6 ] Lethal dosage often varies depending on the method of administration ; for instance, many substances are less toxic when administered orally than when intravenously administered.

“Cleanup at Los Alamos is long delayed,” Coghlan said, adding that annual spending for the plutonium pit work has neared $2 billion in recent years while the cleanup budget for legacy waste is ...
