- it is not recommended to destroy the detector
- it is not recommended to dispose the detector in garbages or in the environment

What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
What the radioactive element is used in smoke detectors?
It's usually americium-241. It undergoes alpha-decay with a half-life of about 400 years. Am-241 is artificially manufactured; it doesn't occur in nature.
Is the radioactive material in smoke detectors dangerous?
Only if you eat it. The substance is americium-241, and it's so small that whatever radioactivity it produces is harmless.
Why the Americium is used in smoke detectors?
In the smoke detector, the fast - moving alpha particles enable the air to conduct an electric current. As long as the electric current is flowing, the smoke detector is silent. The alarm is triggered when the flow of electric current is interrupted by smoke entering the detector.
Why do nuclei that emit alpha particles such as americium-241 are safe to use in smoke defectors?
Nuclei that emit alpha particles, such as americium-241, are safe to use in smoke detectors because alpha particles can only travel a short distance through air and are easily stopped by a thin sheet of paper or clothing. The radiation emitted by the nuclei is low energy and poses no harm to humans. Additionally, the amount of americium-241 used in smoke detectors is very small, further reducing the risk.
How long has americium been used in smoke detectors?
Americium become to be largely used in smoke detectors after 1970.
What household item contains radioactive isotope americium 241?
smoke detectors
Was there americium in the first smoke dectores?
Alpha particles from americium ionized the air. An air with smoke has a different ionization, ionization currents which are also different are measured, compared and the detector (which was before calibrated) is ready ! The americium smoke detectors (with ionization) are not the first smoke detectors.
What has americium?
smoke detectors and x-rays
Where is Americium commonly used?
Americium-241 is a radioactive isotope commonly found in smoke detectors.
What is a radioactive element used is smoke detectors?
Americium 241
A synthetic element that is used in smoke detectors is?
Americium-241 this is an emitter of alpha radiation, which is used in smoke detectors as it is very ionising and will not be able to travel through smoke. Therefore, in a fire the detector will not receive any alpha radiation and hence the alarm will go off.
What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
How is Americium used in are daily life?
americinium is used in smoke detectors to check for smoke
Many smoke detectors contain?
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
What synthetic element that is used in smoke detectors?
Americium (isotope 241) is the most common radioactive element used in smoke detectors.
What element is used in smoke detectors and named for the US?
AMERICIUM 241!
