17 Americium-241(Am) is an artificially produced radioactive isotope which was commonly used in smoke detectors. It decays through emission of an a-particle to neptunium (Np).(a)(i)Complete the nuclear equation which represents the decay of americium.(2)24195Am→Np+0*(ii) Explain why mos...
It tarnishes slowly in dry air at room temperature. Isotope241Am, the most common isotope, decays to237Np, emitting alpha and gamma radiation(1). Uses of Americium Isotope241Am is used (in the form of americium dioxide) in very small amounts in ‘ionization chamber’ smoke detectors. One ...
The same isotope, mixed with beryllium, is used as a neutron source in oilwell logging and other applications. Americium-241 has been used in smoke detectors; its α -emissions ionize the surrounding air and the resulting ions provoke electronic signals when they come into contact with electrodes...
Americium-241 has been used industrially influid-density gauges, thickness gauges, aircraft fuel gauges, and distance-sensing devices, all of which use its gamma radiation. The isotope's alpha-particle emission is exploited in smoke detectors. What household items have Americium? Smoke detectors: mo...
SymbolAmA synthetic, silvery-white, radioactive metallic element of the actinide series that is produced artificially by bombarding plutonium with neutrons. Americium is used as a source of alpha particles for smoke detectors and gamma rays for industrial gauges. Its most stable isotope has a half-...
What is It Used for Small amounts of americium dioxide are used in smoke detectors and alarms[1, 6]. Several isotopes of americium are now investigated on their use as a possible power source for deep space vehicles[1, 3]. It could potentially become the favored fuel source and replace ...
Quick Reference.An isotope produced by the radioactive decay of the nuclei of another isotope(the parent isotope). For example, lead-206 is a daughter isotope of uranium-238, which has a half-life of 4.5 billion years. Why do smoke detectors expire?
from smoke detectors containing americium-241. (Indeed, countless lives a year are saved in the United States because of smoke detectors.) The amount of this isotope in a smoke detector is very small. One gram of americium oxide made with americium-241 will make 5,000 smoke detectors....
used as a tracer in radiochemical applications and analysis. Americium-241 has wider use as a source in ionization chambers in smoke detectors, discharge arresters, and industrial gages. It is also used as a source of alpha particles for production of neutrons in AmBe neutron sources (UNSCEAR,...
