Okay, so, a long time ago, there was a place called Chernobyl. It was a big, big factory where people made electricity. But one day, something very bad happened. There was a big explosion and fire, and lots of dangerous things called radiation came out.
Radiation is like invisible germs that can hurt your body really badly. If you get too close to it, it can make you sick, and even hurt your DNA which is like the instruction manual for your body.
The people who worked at Chernobyl and the people who lived nearby got very sick because of the radiation. They had lots of problems with their skin, their hair, and their bodies couldn't work as well as they used to. Some of them even died.
But that's not all. The environment around Chernobyl was also hurt by the explosion. The soil, water, and air all got contaminated with radiation, which means they were full of germs that could hurt both people and animals.
A lot of plants and animals died or got sick too. Animals like birds, fishes, and deer got exposed to the radiation and it made them very sick. Their babies were also affected because the radiation changed their DNA as well. Even the plants that grew in the area were damaged by the radiation and had strange mutations from the exposure.
So, because of the Chernobyl explosion, lots of people and animals got very sick and the environment around Chernobyl was damaged. It was a very sad and scary time for everyone involved.
