That's because americium is used in many smoke detectors. Fremont is a city in Alameda County, California, United States.It was incorporated on January 23, 1956, from the annexation of Centerville, Niles, Irvington, Mission San José, and Warm Springs. Uncombined elements have an oxidation state of 0. Commercial use of the Images will be charged at a rate based on the particular use, prices on application. Americium is a man-made silver, shiny, chemical compound, classified under the transuranium elements and actinides in the f-block of the periodic table. But before any terrorist groups try to corner the market in smoke detectors it's worth pointing out that it would take around 180 billion of them to have sufficient americium-241 assembled to go critical - and even then it wouldn't be enough to put the detectors together in the same place, you would have to painstakingly extract each of those 180 billion specks of the element and mould them together, an effort that would take thousands of years. This work was carried out at the University of Chicago's Metallurgical Laboratory, now known as Argonne National Laboratory. Values are given for typical oxidation number and coordination. Our americium page has over 115 facts that span 47 different quantities.

Each entry has a full citation identifying its source. Americium didn't exist until Glen T. Seaborg and his colleagues, working on the Manhattan Project in the Metallurgical Laboratory at the University of Chicago, produced it in 1944. The alpha particles flowing from the americium (it's a better alpha source than radium) pass through a small compartment where they ionize the air, allowing a tiny electrical current to cross the chamber. Named for the Americas. You can print the list of elements by hitting the print button below. Sublimation It was produced by the beta-particle decay of plutonium-241, which had been produced in a nuclear reactor by neutron bombardment of plutonium-239.
