The deterministic effect of ionizing radiation on human health can lead to cancer which occurs upon high doses and high dose rates.
Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. Ionizing radiation (ionising radiation) is radiation, traveling as a particle or electromagnetic wave, that carries sufficient energy to detach electrons from atoms or molecules, thereby ionizing an atom or a molecule. deterministic effects (harmful tissue reactions) due in large part to killing or malfunction of cells following high doses from radiation burns. Exposure to ionizing radiation causes damage to living tissue and can result in radiation burns, cell damage, radiation sickness, cancer, and death.
