Radiation is an energy that is produced in the form of particles or waves. It is produced naturally by sunlight, and it is also produced by humans during X-rays, cancer treatments, and in nuclear facilities.

The symptoms are nausea, skin burns, and reduced organ function. In severe cases, it leads to death.
