Biological Effects of Radiation

Course Number: 572


Ionizing radiation generates free radicals. Free radicals interact with biological tissues, most importantly DNA. The severity of radiation-induced damage depends on the cell's sensitivity and the type and dose of radiation. There may be a DNA damage repair, but there are deterministic effects visible over a short-term period and a long-term period. The late somatic effects may manifest as malignancy and other genetic mutations.
