What are the Advantages and disadvantages of ionization type smoke detector?

Ionization smoke detectors are generally more sensitive to fast-flaming fires, making them effective for detecting flames that produce little smoke. They are typically less expensive and respond quickly to combustion particles. However, they can be prone to false alarms from common household activities like cooking, and they may not be as effective at detecting smoldering fires, which can be more dangerous. Additionally, ionization detectors contain radioactive material, raising concerns about safety and disposal.
