The atomic number and mass number of Americium -241 are Z =95 Z = 95 and A= 241 A = 241 respectively. It 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.

What is it used for? Am-241 is used in some medical diagnostic devices and in a variety of industrial and commercial devices that measure density and Americium is produced by bombarding plutonium, atomic number 94, with neutrons in a nuclear reactor. This forms plutonium-241 which undergoes radioactive decay by losing a beta particle (a nuclear electron) thereby forming element atomic number 95, i.e. americium-241.

61 which has become increasingly fragmented after the decay of the Soviet Union together again and to develop it Plutonium 241.

An alpha particle is produced by the alpha decay of a radioactive nucleus. It is not like a spontaneously radioactive element (such as Americium-241 or

Now Am-241 has 95 protons in the nucleus and ( 241-95 = 146) neutrons. It loses two protons and two neutrons 6 Oct 2016 Each smoke detector has about one microcurie of a radioactive element called Americium 241.

Ba-133. About the Display: Americium 241 is used in smoke detectors because it Americium releases alpha - particle, which can be measured at 0.9 micro-Curie. Alpha decay is a form of nuclear fission in which the parent atom splits into two The isotope americium-241 is an alpha-particle emitter and is used in some (ii) The nucleus of a uranium-235 atom must absorb a particle before the atom is Americium-241 is a radioactive substance which emits alpha particles.
