Half life of am241
Americium-241 ( Am , Am-241) is an isotope of americium. Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste. It is commonly found in ionization type smoke detectors … See more Americium-241 has been produced in small quantities in nuclear reactors for decades, and many kilograms of Am have been accumulated by now. Nevertheless, since it was first offered for sale in 1962, its price, about … See more Ionization-type smoke detector Americium-241 is the only synthetic isotope to have found its way into the household, where the most common type of smoke detector (the ionization-type) uses Am O 2 (americium-241 dioxide) as its source of See more • Isotopes of americium See more Americium-241 decays mainly via alpha decay, with a weak gamma ray byproduct. The α-decay is shown as follows: The α-decay energies are 5.486 megaelectronvolts (0.8790 picojoules) for 85% of the time … See more Americium-241 has the same general hazards as other americium isotopes: it is both extremely toxic and radioactive. Although α-particles can be stopped by a sheet of paper, there are serious health concerns for ingestion of α-emitters.
