However, the effectiveness of these devices was never 14 May 2015 NNSA uses worst-case values in this equation, yet median values may Since plutonium-241 is the source of americium-241 in WGPu, 5 Nov 2016 Americium is the only synthetic element to have found its way into the household, where one common type of smoke detector uses 241Am in 22 May 2015 its americium-241 limit, permitting reduction in equipment for that process and reducing worker radiation exposure.

Americium-241 bylo v malých množstvích vyráběno v jaderných reaktorech po desítky let, již jej bylo vyrobeno mnoho kilogramů. Poprvé bylo nabídnuto k prodeji v roce 1962, ovšem jeho cena, kolem 1 500 USD za gram, se od té doby téměř nezměnila kvůli velmi složitému separačnímu procesu. Americium (Am), synthetic chemical element (atomic number 95) of the actinoid series of the periodic table. Unknown in nature, americium (as the isotope americium-241) was artificially produced from plutonium-239 (atomic number 94) in 1944 by American chemists Glenn T. Seaborg, Ralph A.

All these applications use Gamma Ray emission. So, the Gamma radiating properties of this isotope are utilized for these purposes.

Se hela listan på epa.gov Americium-241 is detectable in very small activities over the whole Northern Hemisphere as the result of nuclear weapons tests in the atmosphere in the 1950s and beginning of the 1960s. Very sensitive methods, including radiochemical separation from large samples, are necessary for detection of 241 Am in soil, which may be present in concentrations of 20–40 Bq m −2 . Se hela listan på chemicool.com Americium can be produced in kilogram quantities and has a few practical uses. It is used in smoke detectors and can be used as a portable source of gamma rays. Americium-241, with a half-life of 432.2 years, is used in these products because it is easier to produce relatively pure samples of this isotope.

It decays via alpha emission and spontaneous fission. This means that, after 25 years, about 4% of the original americium in your smoke detector has transmuted into neptunium-237 Americium has found its way into the household, where one type of smoke detector contains a tiny amount (about 0.2 microgram) of 241 Am as a source of ionizing radiation.

What are the uses of americium-241? Americium when blended with beryllium is used as a neutron source in the testing of machinery and in thickness gauges in the glass industry. Americium also is used as a radiation source in medical diagnostic devices and in research. It is commonly used in minute amounts in smoke detectors as an ionization source. How does americium-241 change in the environment?

Americium-241 has been used as a portable source of both gamma rays and alpha particles for a number of medical and industrial uses. The 59.5409 keV gamma ray emissions from 241 Am in such sources can be used for indirect analysis of materials in radiography and X-ray fluorescence spectroscopy, as well as for quality control in fixed nuclear density gauges and nuclear densometers .
