Question

Which type of detector is typically found in aircraft hangars?

Answer 1

Ionization-type smoke detectors, which contain Americium-241, are commonly found in aircraft hangars. These detectors use ionization to detect smoke particles and trigger an alarm.

Step-by-step explanation:

The type of detector typically found in aircraft hangars is a smoke detector. Specifically, an ionization-type smoke detector is commonly used in these environments. These detectors contain a small amount of Americium-241, which emits alpha particles that ionize the air between two electrode plates in the ionizing chamber. When smoke enters the chamber, the movement of ions is impeded, resulting in a drop in current and triggering an alarm.
