Radiation Biology
Content is designed to provide an overview of the principles of the interaction of radiation with living systems. Radiation effects on molecules, cells, tissues, and the body as a whole are presented. Factors affecting biological response are presented, including acute and chronic effects of radiation.
Lara Skaggs
-Differentiate between ionic and covalent molecular bonds.
-Describe principles of cellular biology.
-Identify sources of electromagnetic and particulate ionizing radiations.
-Discriminate between direct and indirect ionizing radiation.
-Discriminate between the direct and indirect mechanisms of radiobiological effects.
-Discuss the direct and indirect effects of ionizing radiation.
-Identify sources of radiation exposure.
-Describe radiation-induced chemical reactions and potential biologic damage.
-Evaluate factors influencing radio-biologic/biophysical events at the cellular and sub-cellular level.
-Identify methods to measure radiation response.
-Describe physical, chemical and biologic factors influencing radiation response of cells and tissues.
-Explain factors influencing radio-sensitivity.
-Recognize the clinical significance of LD 50/30 and LD 30.
-Identify specific cells from the most radiosensitive to the least radiosensitive.
-Employ dose response curves to study the relationship between radiation dose levels and the degree of injury response.
-Examine effects of limited vs. total body exposure.
-Relate short-term and long-term effect as a consequence of high and low radiation doses.
-Differentiate between somatic and genetic radiation effects as well as discuss specific diseases or syndromes associated with them.
-Discuss use and information to be gained from various dose/response curves.
-Discuss stochastic (probabilistic) and non-stochastic (deterministic) effects.
-Discuss embryo and fetal effects of radiation exposure.
-Discuss risk estimates for radiation-induced malignancies.
-Discuss acute radiation syndrome including: dose ranges, manifestations and prognosis.
