Compute the answer to three significant digits. Answer by Cromlix(4380) (Show Source): Nineteen radioisotopes of americium— 223 Am, 229 Am, 230 Am, and those ranging from 232 Am to 247 Am—have been characterized, with the most stable being 243 Am with a half-life of 7,370 years, and 241 Am with a half-life of 432.2 years. Americium was first made late in 1944 at the University of Chicago by a team which included Glenn Seaborg, Ralph James, Leon Morgan, and Albert Ghiorso. The americium was produced by bombarding plutonium with neutrons in a nuclear reactor. This produced isotope americium-241, which has a half-life of this is 432 years. 241 Am has a 437.2 year half-life and its radiological effects far outweigh its chemical toxicity. You should also look at the Centers for Disease Control and Prevention's website and search "americium" for more information.

2004-08-18 · Americium-241 (Am-241) Half-life: 432.2 years Alpha particle: the nucleus of a helium atom, made up of two neutrons and two protons with a charge of +2. Certain radioactive nuclei emit alpha particles. Alpha particles generally carry more energy than gamma or beta particles, and deposit that energy very quickly while passing through tissue. nuclear form is known as the half-life. The half-life of americium-241 is about 432 years. How are people exposed to americium-241?

From Wikipedia, The Free Encyclopedia Americium-241 (241Am, Am-241) is an isotope of americium. Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste. Americium-241, with a half-life of 432.2 years, is used in these products because it is easier to produce relatively pure samples of this isotope.
