This produced isotope americium-241, which has a half-life of this is 432 years. And americium is an important part of it. A small piece of americium oxide made with the americium-241 isotope is sealed inside the smoke detector. The americium-241 gives off alpha particles. The alpha particles strike air molecules, causing them to break apart.

Americium (Am, atomic number 95) is an artificial actinide. Its most important isotope is americium-241 (half-life 432.7 years), which is produced by the beta-decay of plutonium-241. Americium-241 is used commercially in applications such as smoke detectors, thickness gauges, and fluid level gauges.

Det som kallas en kritisk massa i en kärnreaktor. Kritiskt, superkritiskt
Every so often it shoots out an alpha particle - a grouping of two protons and two neutrons. Americium-241 EPA Facts About Americium-241 July 2002 What is americium-241? Americium is a man-made radioactive metal that exists as a solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors and nuclear weapons tests. Americium occurs in several forms called isotopes.

Exposure to a significant amount of Am-241 is generally unlikely. Small amounts are found in the soil, plants and water from nuclear weapons testing. The americium isotope 241 Am is used in smoke detectors. Describe the composition of a neutral atom of this isotope for protons, neutrons, and electrons. Americium-241 and Nuclear densometer · See more » Nuclear isomer. A nuclear isomer is a metastable state of an atomic nucleus caused by the excitation of one or more of its nucleons (protons or neutrons). New!!: Americium-241 and Nuclear isomer · See more » Nuclear reactor Americium-241 decays mainly via alpha decay, with a weak gamma ray product.The α-decay is shown as follows: The α-decay energies are 5.486 MeV for 85% of the time (the one which is widely accepted for standard α-decay energy), 5.443 MeV for 13% of the time, and 5.388 MeV for the remaining 1%.
