2017-02-28 · Facts about Americium 1: The discovery of Americium.
Översättningar av fras IS USED TO MAKE från engelsk till svenska och exempel The isotope, americium-241, is an alphaemitter with a half-life of 432.0 years
Because they use Americium 241, ionization smoke detectors are the most sensitive to invisible particles found in highly dangerous, fast-burning, smokeless 2 Apr 2019 article, we provide radioluminescence images of Am-241 dissolved in single photons can be used for remote detection of alpha radiation. 27 Sep 2009 The equipment used in this first stage was a gamma spectrometer, previously calibrated with an Am-241 standard source, in agreement with the Smoke detectors are the most common consumer product that uses nuclear technology. They work by putting a source of alpha radiation, usually americium- 241 22 Oct 2020 Gamma spectrometry, using High Purity Germanium detectors, is the primary tool used to determine 241 Am at levels of 0.1-1 Bq/kg or higher; 12 Jul 2013 One type of smoke detector -- the one found in most private homes -- uses a very small "button" of americium-241 to detect smoke or other for samples containing only plutonium, and alpha spectroscopy was used for samples containing a mixture of isotopes. For the determination of Am-241 in a Am-241.
americium has proven to be an element that is quite useful. Discussion of the discovery, announcement of and naming of this element, its characteristics, isotopes, applications [including in smoke detectors], use as a portable gamma ray source, and as a fuel for spacecraft will be described. The chemistry of americium and
Americium is commonly used in very small amounts in smoke detectors. It is blended with the element beryllium and is used as a neutron source to measure the quantity of water present in soil, as well as moisture and density for quality control in highway construction. Americium is also used as Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke. 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. The isotope of americium used in smoke detectors is americium-241, which decays by α emission to neptunium-237 with a half-life of 432.2 years.

Americium-241 (241Am) is used in very small quantities in household ionization smoke detectors. Americium is similar to plutonium (Pu) in many ways. While the public accepts the use of minute quantities of 241Am in smoke detectors in their homes, the public reaction to transporting any quantity of 239Pu under suitable controls is very different.
