Americium-241 is a radioactive isotope and used in smoke detectors to ionize the air (gives air molecules a charge). This allows a small current t flow between two contacts placed in the air chamber. When smoke particles enter the chamber, they attach themselves to the ionized molecules (by electrostatic attraction) effectively making them bigger and slowing the current. The detector then goes off when the current slows.
What else can I help you with?
What element is used in smoke detectors and named for the US?
The element used in smoke detectors and named after the US is Americium (Am). It is a radioactive element commonly found in household smoke detectors to detect smoke particles in the air.
How long has americium been used in smoke detectors?
Americium has been used in smoke detectors since the 1950s. Its radioactive properties make it ideal for ionizing smoke particles in the detector, allowing it to quickly detect smoke and trigger the alarm.
A synthetic element used in smoke detectors?
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and is used in smoke detectors.
What synthetic element that is used in smoke detectors?
The synthetic element used in smoke detectors is Americium-241. It emits alpha particles that ionize the air within the smoke detector, causing a small electric current flow. When smoke particles disrupt this current, an alarm is triggered.
What is the element americium used in?
Americium is primarily used in smoke detectors to detect smoke by ionizing air particles. It is also used in some medical devices for radiation therapy and in some industrial measurements for material analysis.
What are smoke detectors?
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.

How long has americium been used in smoke detectors?
Americium has been used in smoke detectors since the 1950s. Its radioactive properties make it ideal for ionizing smoke particles in the detector, allowing it to quickly detect smoke and trigger the alarm.
What gauge wire is used to run smoke detectors?
14-3 Is the standard wire use for residental smoke detectors.
How is Americium used in are daily life?
americinium is used in smoke detectors to check for smoke
What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
Are interlinked smoke detectors a good idea?
There are several types of smoke detectors that can be used in the home. Interlinked smoke detectors can interlink smoke and heat detectors for better convenience. Also, wireless units can be configured specifically to your needs. More safety and smoke detector information can be found on: http://www.safelincs.co.uk/Smoke-Alarms/

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 is a radioactive element used is smoke detectors?
Americium 241
Which zone is used for smoke or heat detectors?
panic zone
