Nuclear and radiation accidents and incidents

Nuclear and radiation accidents and incidents are when something goes wrong at a nuclear power plant or other place that uses nuclear power or radiation. This could mean something leaking or spilling out, or an explosion happening. When this happens, it can be dangerous because it can send out a lot of dangerous radiation into the air, which can make people sick and even cause cancer. This is why it's important to make sure these places are very careful and well-maintained so they never have accidents.
