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. 241Am is...

than 241 Am, the former is harder to obtain than the latter as more of it is present in spent nuclear fuel. Eighteen radioisotopes of americium, ranging...

madness). Initial experiments yielded four americium isotopes: 241Am, 242Am, 239Am and 238Am. Americium-241 was directly obtained from plutonium upon absorption...

spent nuclear fuel waits before reprocessing, the more 241Pu decays to americium-241, which is nonfissile (although fissionable by fast neutrons) and an...

detector contains about 37 kBq (1,000 nCi) of radioactive element americium-241 (241 Am ), corresponding to about 0.3 μg of the isotope. This provides...

the most common household smoke detectors. The radionuclide used is americium-241, which is created by bombarding plutonium with neutrons in a nuclear...

241 is a repdigit in base 15 (111). 241 is the only known Lucas–Wieferich prime to (U, V) = (3, −1). Americium-241 is an isotope commonly used in smoke...

plutonium. In particular, plutonium-241 decays to americium-241 with a 14-year half-life. Because americium-241 is a gamma ray emitter,[citation needed]...

isotopes of these elements in spent nuclear fuel are neptunium-237, americium-241, americium-243, curium-242 through -248, and californium-249 through -252...

neutron probe contains a pellet of americium-241 and beryllium. The alpha particles emitted by the decay of the americium collide with the light beryllium...
