Radiation Exposure

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. Long-term exposure to a small amount of radiation causes gene mutations and increases the risk of developing cancer. Brief exposure for a longer period causes radiation sickness. The symptoms are nausea, skin burns, and reduced organ function. In severe cases, it leads to death.
