According to NFPA 72, the national fire code, smoke detectors shall be installed in each sleeping area, outside each sleeping area, and on each story of a home, i.e. top and bottom of stairways.
The first smoke detectors are based on optical principles - photoelectric detectors.
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
You can properly dispose of smoke detectors at Lowe's by bringing them to the customer service desk for recycling.
Old smoke detectors should be properly disposed of according to local regulations. Many manufacturers offer recycling programs for old smoke detectors to ensure they are disposed of safely and responsibly. Contact the manufacturer or your local waste management facility for guidance on how to properly dispose of old smoke detectors.

Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
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.
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.

americinium is used in smoke detectors to check for smoke
The first smoke detectors are based on optical principles - photoelectric detectors.
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/
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and 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.
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.
