Americium-241, on the other hand, only has about a quarter of the power output that plutonium has, but it has a longer half-life (433 years), more easily produced, and can potentially bring cost

Abstract. Theoretically, alpha and gamma emission rates of Am-241 are intense enough to be actually used through three different radioactive measuring

243 This includes public education and materials related to radionuclides, like the ones that are used in ionization smoke detectors. Radionuclides Basics: Americium-241 This webpage provides basic scientific information on americium as well as information on human exposure, health effects, and protecting people from radiation. 2008-03-29 The ionization chamber has found wide and beneficial use in smoke detectors. In an ionisation type smoke detector, ambient air is allowed to freely enter the ionization chamber.

certified quantity of radioactive Americium‐241 is dissolved. It is intended primarily for the calibration of instruments that are used to measure radioactivity and for the monitoring of radiochemical procedures. The solution is contained in a flame sealed, 5 mL, NIST, borosilicate glass ampoule. Company Information

The symbol used to denote this radioactive isotope is 241Am or Am-241. Americium-241 Production. These days, the isotope is produced artificially as a decay product of Plutonium-241. It is also a resultant material of nuclear bomb explosions.

No commercial uses for other americium isotopes were found. However, 243. Am can be used as a target material for the production of transcurium elements in high neutron flux reactors (Budavari 1996). 243 2008-03-29 The first isotope of americium produced was americium 241, still the most commonly used form. The Manhattan Project was busy creating plutonium to be used in nuclear weapons, and some plutonium 239 went through a process of capturing extra neutrons to become 240 and then 241, which gave off an electron from the nucleus to turn into americium.

To measure counts of This drop in measurement will trigger the alarm to sound. Americium-241 is the most common material used as the alpha emitter in a domestic smoke alarm.

Americium-241, an α emitter with a half-life of 458 years, is used in tiny amounts in ionization-type smoke detectors (Figure 3.14). The α emissions from Am-241 ionize the air between two electrode plates in the ionizing chamber. A battery supplies a potential that causes movement of the ions, thus creating a small electric current.
