What is americium-241 used in?
smoke detectors
Americium-241 is used as a neutron source in non-destructive testing of machinery and equipment, and as a thickness gauge in the glass industry. However, its most common application is as an ionization source in smoke detectors, and most of the several kilograms of americium made each year are used in this way.
Which element is formed when an alpha particle is emitted from americium-241?
neptunium-237 atom
An alpha particle is made up of two protons and two neutrons bound together, which is the equivalent of a helium-4 nucleus. In the process of emitting the alpha particle, the americium-241 atom becomes a neptunium-237 atom.
Is Am-241 a transuranic?
Also 17 reactors dumped in the Kara Sea are potential sources of transuranic elements, including 241Am.
What is the 95th element?
The New Element Americium (Atomic Number 95)
Can you eat americium?
Some americium that enters your lungs may get into your blood. If you swallow americium, a very small amount of what enters your digestive tract may also enter your blood.

Why is Am-241 used in smoke alarms?
Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. Smoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector’s alarm. They react quickly to fires that give off little smoke.
What isotope is used in smoke detectors?
americium-241
Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke.
What is the symbol of radon?
RnRadon / Symbol
radon (Rn), chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium.
What is RA in periodic table?

What are 3 elements named after a continent?
Americium was named after the Americas. Europium was named after Europe. Berkelium was named after American city Berkeley. Tennessine and Californium were named after American states Tennessee and California respectively.
What is this uranium-235?
Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide.
Do smoke detectors still used americium?
Most smoke detectors use americium-241 as their source. Some early models used radium-226, and commercial smoke detectors and some residential units used nickel-63. The types of radiation from these sources cannot make anything else radioactive.
What is americium 241 Am?
Americium 241 Am is a beta decay product from 241 Pu produced in nuclear reactors. 241 Am coexists with plutonium except for freshly separated Pu. 241 Am emits an extremely intense gamma ray at 59.5 KeV, but this line is easily shielded. A less intense line at 125 KeV also exists, but this line is also fairly easily shielded.
What are the parent nuclides of americium 241?
Its common parent nuclides are β − from 241 Pu, EC from 241 Cm, and α from 245 Bk. 241 Am is fissile and the critical mass of a bare sphere is 57.6–75.6 kilograms and a sphere diameter of 19–21 centimeters. Americium-241 has a specific activity of 3.43 Ci/g ( curies per gram or 126.8 gigabecquerels (GBq) per gram).
What is the chemical formula for americium americium?
Analogous to uranocene, americium forms the organometallic compound amerocene with two cyclooctatetraene ligands, with the chemical formula (η 8 -C 8 H 8) 2 Am. A cyclopentadienyl complex is also known that is likely to be stoichiometrically AmCp 3.
Does americium 241 undergo fission or fission?
The second most common type of decay that americium-241 undergoes is spontaneous fission, with a branching ratio of 3.6×10 −12 and happening 1.2 times a second per gram of 241Am. It is written as such (the asterisk denotes an excited nucleus):
