Course Desciption

The course develops an awareness of the potential hazards in radiation departments and its immediate surroundings. It ensure that the student takes reasonable preventive remedial measures, and that he knows the action he should take when an accident occurs, having due regard to the result of this action on the normal functioning of the department. It provides students with the basic theory of hazards of radioactivity and precaution taken to minimize the risk. It provides students with radiation measurement how to deal with radiation accident and emergencies in nuclear medicine department

Course Objectives

To make the student aware of the possible dangers that exist in a radiological or therapeutic department or any area where ionizing radiation is used for medical or dental use. Also, to enable the student to deal correctly and effectively with these dangers. On completion of this course the student will be able to monitor radiation and contamination and be able how to deal with, and will be able to understand basic principles of radiation safety
