(a) Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products. Americium-241, an alpha source.

Np is the symbol for neptunium. Complete the nuclear equation for the decay of americium-241. (3) + 241 Am 95 Np 237 .

It is an alpha emitter with a half-life of 432 years . How long will it take in years for 31.0 % of an Am-241 sample to decay?Express your answer numerically in years. Americium-241 is an alpha emitter with a half-life of 432.6 years. Alpha particle radiation, as opposed to beta (electron) and gamma (electromagnetic) radiation, is used for two reasons: alpha particles have more ionizing power, so as to ionize enough air to make a detectable current, and they have low penetrative power, meaning they will be stopped, safely, by the plastic of the smoke Americium-241 is used in smoke detectors, but its radiation poses little threat.

The most widespread use of 241AmBe neutron sources is a neutron probe – a device used to measure the quantity of water present in soil, as well as moisture/

that are by far the most useful are cobalt-60, caesium-137, technetium-99m and americium- 24 Americium 241 based smoke detectors work because of the radioactivity of the 241Am isotope.

3 Apr 2009 Americium-241 is the only isotope of americium to have widespread commercial use. It is the radiation source for a number of applications:.

Internationellt. 112. 115. 88. 116. Referee test Platforms for Infectious Diseases”. Projektet ska Transmutation of Americium in Fast Neutron Facilities catalytic strategies used by enzymes.

For instance, a small piece of americium-241 can be placed above a conveyor belt carrying newly made glass. Smoke detectors are common household items that keep you and your family safe by alerting you to smoke in your home. Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke. 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. (The isotope americium-243 also decays by α emission and is longer-lived at 7370 years, but it is obtained americium-241. What are the uses of americium-241?
