Answer

Brief Explanations:

Smoke detectors contain a small amount of radioactive material (americium - 241). This radioactive source ionizes the air in the detector chamber. When smoke enters, it disrupts the ion - current, triggering the alarm. Conventional ovens use heat for cooking, electric air filters use electrostatic forces, and computers/TV sets use electrical signals and electromagnetic radiation in non - radioactive ways.
