Please and Thank you! of Energy (DOE) environmental management sites: americium-241, americium-242m, and americium-243. The half-lives of these three isotopes range from 150 to 7,400 years, while those of the other isotopes are less than a day. Americium-241 is generally the most prevalent isotope at DOE sites such as Hanford. It has a half-life of 430 years and decays The mean half-life ratio was found to be 16.70 plus or minus 0.10, corresponding to a half life of 7650 plus or minus 50 years for Am/sup 241/. 2017-01-17 · Americium-241 is used in smoke detectors. It has a first–order rate constant for radioactive decay of k = 1.6 * 10-3 yr-1.

Homework Statement The half life of americium-241 is 457.699 years. A typical smoke detector contains 33.1 kBq of americium-241. Determine the amount of americium-242 remaining after 15 years. Homework Equations A=Aoe - - 0.693t/T 1/2 The Attempt at a
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.
