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.
The learning out comes of this course are:-
- The principles of radiation protection
- The biological effects of ionizing radiation
- students will learn how to calculate the radiation exposure and dose, monitoring the environmental radiation
- Utilized instrumentation used for radiation exposure monitoring.
- Designing and control the radiation shielding
