Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
It is the acid anion that influences the degree of complexing—how atoms connect to a central atom—of the plutonium species. Additionally, the formal +2 oxidation state of plutonium is known in the complex [K(2.2.2-cryptand)] [Pu II Cp″ 3], Cp″ = C 5 H 3 (SiMe 3) 2. [5] A +8 oxidation state is possible as well in the volatile tetroxide ...
Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).
To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
The work followed mapping done by the group earlier this year that was based on a Los Alamos National Laboratory database including plutonium samples from throughout the area.
There are many different varieties of abnormal reactions to blood transfusion. Among these, a potentially life-threatening reaction is known as a hemolytic transfusion reaction. This is an immune mediated reaction where recipient antibodies attack donor red blood cell antigen(s), causing hemolysis of donor cells.
Feb. 5—Two workers suffered skin contamination in separate incidents last month at Los Alamos National Laboratory's plutonium facility, the latest in a series of worker-safety lapses at the lab.
