What are onset type and warning of nuclear disaster?

Answer 1

Onset types of nuclear disasters can be categorized as immediate, such as a reactor core meltdown or explosion, and gradual, such as slow radiation leaks or contamination over time. Warnings of a nuclear disaster may include abnormal readings of radiation levels, unusual activity at nuclear facilities, or seismic events that could compromise reactor integrity. Public alerts may be issued through government channels, emergency broadcasts, and sirens, prompting evacuation or shelter-in-place orders. Effective communication and preparedness are crucial to mitigate the impact of such disasters.
