Development and Applications of some Radioanalytical Procedures

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. Americium-241 EPA Facts About Americium-241 July 2002 What is americium-241? Americium is a man-made radioactive metal that exists as a solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors and nuclear weapons tests. Americium occurs in several forms called isotopes.

The ionization chamber is the simplest of all gas-filled radiation detectors, and is widely used for the detection and measurement of certain types of ionizing radiation; X-rays, gamma rays, and beta particles. Americium-241 is useful for a wide range of industrial gauging applications and for diagnosing certain thyroid disorders. It is used worldwide to measure the rate of production by oil wells. The predominant commercial use is in ionization-type smoke detectors. /Americium-241/ That's because americium is used in many smoke detectors. A tiny quantity - less than a millionth of a gram - of americium 241 oxide will be sitting in there, beaming out radiation as it slowly transforms to neptunium with a half life of 432 years.

As an alpha emitter, it is mixed with beryllium to produce a neutron source for oil-well logging and to measure water content in soils and industrial process streams.

/Americium-241/ The gamma rays from americium-241 are used in portable X-ray machines that can, for example, be taken into oil fields to help determine where new wells should be dug. Americium-241 is also used to measure the thickness of materials. For instance, a small piece of americium-241 can be placed above a conveyor belt carrying newly made glass.

Half-life Detection and Measurement It is widely used as a component in ionizing. Problem: Americium-241 is used in a number of smoke detectors; as this radioisotope decays it causes particles to ionize, conduct an electric current and Solved: Americium-241 is used in smoke detectors. It has a first-order rate constant for radioactive decay of [math]k = 1.6 \times 10 ^ { - 3 } \mathrm { yr } ^ { - 1 } Solved: Americium-241 is used in smoke detectors.
