Radiation is a type of energy that is released by atoms. It can be harmful to human health, so it is important to take steps to avoid exposure. There are two main types of radiation: ionizing radiation and non-ionizing radiation. Ionizing radiation has enough energy to remove electrons from atoms, which can damage cells and DNA. Non-ionizing radiation does not have enough energy to remove electrons from atoms, but it can still be harmful to human health.
The most common sources of ionizing radiation are medical imaging procedures, such as X-rays and CT scans. Other sources of ionizing radiation include nuclear power plants, uranium mining, and air travel. Non-ionizing radiation is emitted by a variety of devices, including cell phones, microwaves, and televisions. It is also emitted by the sun.
