Americium-241 (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 . 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste .
The critical masses of the two readily available isotopes, 241 Am and 243 Am, are relatively high – 57.6 to 75.6 kg for 241 Am and 209 kg for 243 Am. [97] Scarcity and high price yet hinder application of americium as a nuclear fuel in nuclear reactors.
Americium-241 is the most common isotope of americium in nuclear waste. [8] It is the isotope used in an americium smoke detector based on an ionization chamber.

Americium-241 has been used as a source of low energy gamma photons, it has been used in some applications such as portable X-ray fluorescence equipment and common household ionizing smoke detectors. Americium-241 is produced from 239
Liberals accuse elderly husband of US senator of snubbing Harris’ handshake — here’s what really happened
The most important isotopes of these elements in spent nuclear fuel are neptunium-237, americium-241, americium-243, curium-242 through -248, and californium-249 through -252. Plutonium and the minor actinides will be responsible for the bulk of the radiotoxicity and heat generation of spent nuclear fuel in the long term (300 to 20,000 years in ...
