in the United States. The type of detector I am concerned with is the one containing the isotope of Americium Am-241. This can be seen to the right in Fig. 1. The Am-241 is contained in an ICSD (ionization chamber smoke detector). Most of these detectors use approximately 0.25
How a Smoke Detector Works · The unstable isotope of americium, americium- 241, undergoes nuclear decay to produce neptunium-237 and an alpha particle ( a
Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke. Americium-241 is the only synthetic isotope to have found its way into the household, where the most common type of smoke detector (the ionization-type) uses 241 AmO 2 (americium-241 dioxide) as its source of ionizing radiation. 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 in smoke detectors as an ionization source. How does americium-241 change in the environment?
Läser in. Skydd mot mjuk strålning från 241 Am är relativt enkelt och icke-massivt: ett Sedan 241 Pu vanligtvis finns i nyutvecklat vapenkvalitet plutonium, 241 Am Det finns väldigt lite av det i denna sensor och därför, om du inte tar isär den, är det använder sig av en radioaktiv källa, Americium-241 för att upptäcka rök.

How does americium-241 change in the environment? Americium-241 … Use Early detection of smoke. Radionuclide Americium –241 (Am-241).
Most smoke detectors contain a small amount of Americium 241, a radioactive material. Americium is an alpha emitter, which does not travel very far, even in air .
The Am-241 is contained in an ICSD (ionization chamber smoke detector). [1] Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. Smoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector’s alarm. The US Nuclear Regulatory Commission (NRC) regulates the use and distribution of smoke detectors.

Americium-241 Alpha foil and sources for smoke detectors Americium-241 (241Am) alpha partical emitting foil,made by AEA Technology,is widely used in ionization chamber smoke detectors (ICSD).The foil combines high integrity of containment with high emission efficiency. AEA Technology has over 30 years experience of foil
They react quickly to fires that give off little smoke. Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year.
Americium-241 is the only synthetic isotope to have found its way into the household, where the most common type of smoke detector (the ionization-type) uses 241 AmO 2 (americium-241 dioxide) as its source of ionizing radiation. 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 in smoke detectors as an ionization source. How does americium-241 change in the environment? Americium-241 is formed in the environment by the decay of plutonium contamination from nuclear weapons production and testing. Americium-241 is an unstable isotope.
