NE 430 : Health Physics

Overview

Quantities and Units ( Exposure, Absorbed Dose, Dose Equivalent, Committed Dose Equivalent, Quality factor, effective dose, committed effective dose, and KERMA, Exposure measurement ( free air chamber and air wall chamber). Absorbed dose measurements:- Bragg – Gray principle. Charged particle beam. Dose calculation, Alpha and low energy beta emitter distributed in tissue, charge particle beam, point source of gamma rays and neutrons. Exposure-Dose relationship. Dosimetry of radio nuclides. Health physics Instrumentation ( Personal monitoring, pocket dosimeter, film badges, TL dosimeters, Electronic Dosimeters, Survey Meter and neutron Dosimetry). Radiation Protection : Objectives of radiation protection, Philosophy of radiation protection. Organization that sets standards: International Commission on Radiological protection (ICRP), International Atomic Energy Agency (IAEA) , International Commission on Radiological units and measurements, ICRP basic radiation safety criteria, Local Regulations, External Radiation Protection (time, distance and shielding). Internal Radiation Protections:-Principles of control, Surface contamination, Waste management, Protection guides for non ionizing radiation. Chemical and Biological Effects of Radiation: Dose response characteristics, Direct and Indirect Action, Factors Effecting dose responses (relative biological effectiveness, dose rate and oxygen enhancement ratio), Biological basis for Internal Dosimetry, Biokinetic Processes, Organ system, Unity of the body Radiation Effects:- Acute effects, Delayed effects, Genetic effects Risk coefficient Estimates.
