Nuclear contamination

Nuclear contamination is when dangerous and harmful particles, called radiation, spread out into places where they shouldn't be, like the air we breathe, the food we eat, or the water we drink. These particles are very tiny and invisible, but they can hurt us and make us very sick.

Sometimes, they can escape from a nuclear power plant, which is like a big factory that generates electricity by using radioactive materials. A nuclear power plant has lots of safety measures to prevent this from happening, like thick walls, special containers, and sensors.

But if something goes wrong, like an explosion or a leak, then the radiation can go out into the environment, and this is when it becomes dangerous for people and animals. This is what happened in Chernobyl and Fukushima, two famous accidents that caused a lot of damage.

Nuclear contamination can affect different parts of our body, like our skin, our lungs, our stomach or our bones, depending on how we were exposed to it. It can cause burns, nausea, vomiting, or diarrhea, and it can even give us cancer or damage our DNA.

That is why we need to be very careful with nuclear power and make sure that it is used safely and responsibly, and that we have plans in place to protect ourselves in case of an emergency.
