is that plutonium is highly toxic. By toxic, I’m putting aside the fact that it can be highly radioactive. Just as an element, plutonium is very poisonous and it is about as toxic as nerve gas. It can accumulate in a person’s bones and it is something you really don’t want to ...

Plutonium (pronounced /pluːˈtoʊniəm/ ploo-TOE-nee-əm) is a rare transuranic radioactive chemical element with the chemical symbol Pu and atomic number 94. It is an actinide metal of silvery-white appearance that tarnishes when exposed to air, forming a dull coating when oxidize...
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. ...
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 ...
The greater part of the most dangerously radioactive long-lived radionuclides (strontium-90 and transuranium elements such as isotopes of plutonium and americium) was localized in the vicinity of the destroyed reactor. 辐射最危险的长寿命放射性核素(锶-90和诸如同位素钚和镅等超铀元素)被封闭在损毁反...
Plutonium is an element with rich coordination chemistry, known for its complex behavior and various isotopes, such as plutonium-238, plutonium-239, and plutonium-240, all of which are radioactive. It can exist in five different oxidation states and reacts with almost every element in the Perio...
Alpha decay, the release of a high-energy helium nucleus, is the most common form of radioactive decay for plutonium.[7] A 5 kg mass of 239Pu contains about 12.5×1024 atoms. With a half-life of 24,100 years, about 11.5×1012 of its atoms decay each second by emitting a 5.157 MeV...
Naturally-occurring radium is about 200 times more radiotoxic than plutonium, and some organic toxins like Botulism toxin are billions of times more toxic than plutonium. The alpha radiation it emits does not penetrate the skin, but can irradiate internal organs when plutonium is inhaled or ...
