Radiation is energy that comes from tiny, invisible particles called atoms that make up everything around us, including our own bodies. Sometimes these particles can escape the atoms and travel through the air or even into our bodies.
Radiation can be helpful, like when doctors use X-rays to take pictures of bones, but it can also be harmful, especially if we're exposed to too much of it.
Radiation biology is the study of what happens to living things, like plants and animals, when they're exposed to radiation. Scientists want to figure out how much radiation is safe for people to be around, and what kinds of effects radiation can have on our bodies, such as causing cancer or damaging our cells.
To figure all this out, scientists use special equipment to measure radiation levels and to study how it affects different parts of the body. They might even use tiny creatures like fruit flies to study radiation biology, since these creatures have similar cells to humans and can help us understand more about how radiation affects living things.
In the end, the goal of radiation biology is to make sure we stay safe from harmful radiation and to find ways to protect ourselves from it. So, always remember to listen to your parents, teachers, doctors or any adult who tells you to stay away from areas with too much radiation, as too much of anything can be bad for us.
