Radiation poisoning is when someone is exposed to too much radiation. Radiation is a type of energy that travels in waves and can be found in X-Ray machines and nuclear power plants. When too much radiation is absorbed into the body it can lead to health problems like nausea, vomiting, hair loss, and in extreme cases, death. Radiation poisoning can be prevented by wearing protective clothes when working with radiation, keeping a safe distance away from radiation such as X-Ray machines, and making sure to only use reliable sources of radiation, such as those from nuclear power plants that have safety regulations in place.
