"Radiobiology is a field of clinical and basic medical sciences that involves the study of the effects of ionizing radiation on living things, in particular health effects of radiation."
Describes the way ionizing radiation interacts with biological systems at the cellular and molecular levels.
Atomic and Nuclear Structure: Understanding the fundamental building blocks of matter and the fundamental forces that govern their interactions.
Types of Radiation: Understanding the different types of radiation, e.g., alpha, beta, gamma, and their properties.
Sources of Radiation: Understanding the sources of radiation, e.g., cosmic rays, natural sources, and man-made sources.
Units and Measurements: Understanding the units and measurements used to quantify radiation and its effects, e.g., radiation dose, absorbed dose, and equivalent dose.
Interaction with matter: Understanding the various ways in which radiation interacts with matter, e.g., ionization, excitation, and radiation damage.
Biological effects: Understanding the biological effects of radiation on living organisms, e.g., cell damage, tissue damage, and cancer.
Dose-Response Relationships: Understanding the relationship between the amount of radiation and its effects on living organisms.
Radiation Protection: Understanding the principles and methods of radiation protection, e.g., shielding, time, and distance.
Radiation Therapy: Understanding the use of radiation for therapeutic purposes, e.g., cancer treatment.
Radiation Safety: Understanding the safety procedures and regulations regarding the handling and use of radiation.
Ionization: Radiation transfers energy to an atom or molecule, resulting in the removal of an electron and the formation of an ion.
Excitation: Radiation transfer energy to an atom or molecule, resulting in an excited state but no ion formation.
Radiolysis: Radiation breaks apart molecules by ionization, resulting in the formation of free radicals.
Scattering: Radiation collides with atoms or molecules, causing a change in direction without energy transfer.
Absorption: Radiation is absorbed by the matter, causing excitation or ionization of the atoms or molecules.
Photoelectric effect: Radiation is absorbed by an atom, causing the ejection of an electron.
Compton effect: Radiation collides with an electron, transferring some energy to it and causing a change in direction.
Pair production: Radiation with high energy is absorbed by matter, producing a positron and an electron.
Annihilation: A positron collides with an electron in matter, producing gamma rays.
Bremsstrahlung: Electrons are slowed down or stopped by matter, producing radiation in the form of X-rays.
"Ionizing radiation is generally harmful and potentially lethal to living things."
"Ionizing radiation can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis."
"Its most common impact is the induction of cancer with a latent period of years or decades after exposure."
"High doses can cause visually dramatic radiation burns, and/or rapid fatality through acute radiation syndrome."
"Controlled doses are used for medical imaging and radiotherapy."
