Radiation Protection & Radiobiology NotesHuman Biology Human Response To Ionizing Radiation Early Effects of Radiation: When response occurs within minutes or days after exposure. Late Effects of Radiation: When response is not observed for many months or years after exposure. Effects of fetal irradiation: Death, malformation, malignancy, diminished growth. Composition of Human Body Cell Theory: 85% of the body is hydrogen and oxygen. Hydrogen: 60% Oxygen: 25.7% Carbon: 10.7% Nitrogen: 2.4% Molecular Composition Water: 80% - A simple molecule. Protein: 15% - A macromolecule. Fat: 2% - A macromolecule. Other: 3% Tissues and Organs: (The most radiosensitive cells in the human body are Lymphocytes & Spermatogonia.Fundamental Principles of Radiobiology Law of Bergonie and Tribondeau 1) Older cells are more radioresistant. 2) Younger cells are more radiosensitive. How these principles apply to radiation safety: The fetus is more radiosensitive to radiation than a child or adult. Biologic Factors Affecting Radiosensitivity Age: Humans are most sensitive before birth. Gender: Females are less radiosensitive than males.Molecular and Cellular Radiobiology Irradiation of Macromolecules: (p.450) Follows a Linear, Non-threshold dose/response relationship. Radiation Effects on DNA: DNA is the most radiosensitive macromolecule. 1) Cell death 2) Malignant disease 3) Genetic damage Radiolysis of Water: Indirect Effect. Most prevalent in humans. We are mostl
