Radiation sickness is a serious health condition that happens when a person is exposed to a large amount of radiation. Radiation is a type of energy that can be harmful to our bodies if we are exposed to too much of it. When people in Hiroshima were hit by the atomic bomb in 1945, they were exposed to a huge amount of radiation, which made many of them very sick.
When the atomic bomb exploded, it released a lot of radiation into the air. This radiation spread over the city and affected thousands of people. Those who were closer to the explosion were the most affected by the radiation. People who were exposed to the radiation developed symptoms such as nausea, weakness, hair loss, and even bleeding from their gums and skin. This made it very hard for them to do everyday things like go to school or work, and many became very ill.
Imagine that you are playing outside, and suddenly you feel very sick. You start to feel very tired and your skin turns red. Your hair starts falling out, and you feel like you can't eat anything without feeling sick. This is how some of the people in Hiroshima felt after they were exposed to the radiation from the atomic bomb.
The impact of radiation sickness on the people of Hiroshima was very devastating. Many people got very sick and had to go to the hospital for a long time. Some people even lost their lives because their bodies couldn't handle the effects of the radiation. People who survived also had to deal with long-term health problems caused by the radiation, such as an increased risk of cancer and other illnesses.
Even today, many people in Hiroshima and other places affected by nuclear disasters still live with the effects of radiation sickness. It's a reminder of how dangerous radiation can be and why it's important to use it safely and responsibly.
