Here’s how it works. Plutonium is the 94th element in the periodic table (Image credit: Getty images) Jump to: Origins Power Discovery Uses Additional resources Bibliography Plutonium is radioactive, but it doesn't seem that harmful at first glance. It looks like any other metal, with ...
Plutonium is a radioactive actinide metal whose isotope, plutonium-239, is one of the three primary fissile isotopes (uranium-233 and uranium-235 are the other two); plutonium-241 is also highly fissile. To be considered fissile, an isotope's atomic nucleus must be able to break apart or ...
Plutonium (CAS 7440-07-5) is an alpha-emitting transuranic element that exists as a solid under normal conditions. There are approximately 15 different isotopes of plutonium, all of which are radioactive. Plutonium-238, plutonium-239, an... YR Rodriguez - 《Encyclopedia of Toxicology》 被引量...
PLUTONIUM has emerged into the public gaze again in the past year or so not only because of disquieting reports of lax security at places where it is stored in the United States but also because of fears that the radiation safety standards for the substance, in particular its radioactive ...
As I mentioned before, plutonium-238 is highly radioactive. This isn’t the isotope that is used in bombs. Because it has such a short half-life of only 87 years, it generates a lot of heat. Plutonium-238, if just left to itself, will glow red hot. Hot enough to boil water. More...
Plutonium is an element where the 5f electrons are the transition border between delocalized and localized; it is therefore considered one of the most complex elements.[16] It is a radioactive actinide metal whose isotope, plutonium-239, is one of the three primary fissile isotopes[17] (uranium...
Plutonium is defined as a radioactive silver metal with the atomic number 94. It is radioactive, which means that its ...
It is becoming increasingly apparent, however, that the two plans for disposing of plutonium put forth so far--recycling it in mixed uranium-plutonium oxide (MOX) fuel or immobilizing it along with highly radioactive waste--may be insufficient. The mixed-oxide route is impeded in key ...
Radioactive materialcan be transported by truck, train, plane or ship. There are special regulations that help keep drivers, the public, and the environment safe. The packaging used to transport radioactive material is tested to make sure it will keep people safe if there is an accident. ...
It is radioactive, poisonous, pyrophoric, and capable of accumulating in bones, which makes the handling of neptunium dangerous. Although many false claims of its discovery were made over the years, the element was first synthesized by Edwin McMillan and Philip H. Abelson at the Berkeley ...
