what type of radioactive decay is used in smoke detectors?\na. alpha decay\nb. beta decay\nc. transmutation\nd. positron

Answer

Brief Explanations:

Smoke detectors often use americium - 241 which undergoes alpha decay. Alpha particles ionize the air in the detector chamber. When smoke enters, it disrupts the ionized air flow, triggering the alarm.

Answer:

A. Alpha decay
