Nuclear anxiety is the feeling of fear or worry that people have when they think about nuclear weapons. Nuclear weapons are very powerful bombs that can destroy entire cities and kill a lot of people.
When people hear about nuclear weapons, they might get scared and anxious because they know how dangerous they are. They might worry that a nuclear war could happen and that it could cause a lot of destruction and death.
Nuclear anxiety can also be caused by the fear of nuclear accidents. Nuclear power plants use nuclear reactions to generate electricity, but sometimes accidents can happen that release dangerous radiation into the environment.
Even though nuclear anxiety is a scary feeling, it's important to know that countries and organizations around the world are working hard to prevent nuclear war and nuclear accidents. They are also working to make sure that nuclear weapons are reduced and eliminated over time.
