Web30 Dec 2003 · Rhian B. Cope, in Handbook of Toxicology of Chemical Warfare Agents (Third Edition), 2024 24.9 Home detectors. Residential CO detectors are designed like smoke detectors and provide protection from excessive CO concentrations inside homes by sounding alarms. They are based on an interactive-type sensor, such as tin oxide or … WebSmoke detectors are the most common consumer product that uses nuclear technology. They work by putting a source of alpha radiation, usually americium-241, near an ion detector. The alpha particles ionize the air molecules. That is, they separate an electron from the rest of the molecule, leaving the two halves with an electric charge. business letter sign off
