Maximum biological damage is caused by exposure to high-energy radiation. Also called ionizing radiation, the biological damage caused by exposure to these particles are tremendous. Minor doses of radiation can cause radiation sickness, while higher doses may cause death. At the cellular level, high-energy radiation can effectively destroy the DNA. This can cause the muscles and tissues to die and rot, while the person is still alive. However, the mortality rate depends on the type of radiation, the proximity to the exposure, and the radiation dose absorbed.
