Ionization detectors use a very small amount of radioactive material inside of an ionization chamber with electrically charged plates. When smoke gets into the ionization chamber, it disrupts the flow of ions between the plates and a current can no longer pass through. When that happens, the alarm is activated. Ionization detectors can pick up sma...
