| Outline and Purpose of the Course | Lectures will be given on properties of radiation, the interaction between radiation and matter, the effects of radiation on human beings and organisms, the exposure dose limit, radiation shielding, radiation sources, treatment, radiation protection methods, radiation environment monitoring, engineering problems related to environmental radioactivity, and its impact assessment method. | |||
| Course Goals | Based on the basic knowledge on radiation and radioactivity, understanding the radiation sources in the living environment, the characteristics of radiation exposure, the characteristics of biological influences, and the way of thinking about setting radiation exposure limits. Based on this basic knowledge, understanding the framework of exposure control, environmental monitoring, and environmental radiation risk assessment according to the characteristics of radiation and radioactivity. | |||
| Schedule and Contents |
Radiation and radioactivity (3 times): The purpose and system of radiological health engineering, its definition, the composition of lecture contents, and current radiation related issues will be outlined. In addition, the mechanism of nuclear collapse and the emission of radiation, the stability of atomic nuclei, types and energies of radiation, collapsed series, and so forth will be covered. Interaction of radiation and matter (3 times): Mechanism and characteristics of interaction between α rays, β rays, and γ rays, characteristics of radiometers, nuclear reactions, collapse diagrams, principles of activation analysis, and so forth will be discussed. Additionally, lectures will be given on the shielding of gamma rays, the kind and thickness of shielding material, the method of external radiation dose assessment by ionizing radiation, and so forth. Biological/human body effect of radiation (2 times): The mechanism of the influence of radiation on living beings from DNA, cells, and the solid level will be explained. Radiation effects on the human body will be classified, and the concept of radiation protection, exposure limit value and risk, the method of setting exposure limit values, the regulated values by law, methods to avoid radiation exposure, and so forth will be covered. Method of radiation management (3 time): Radiation effects on the human body will be classified and a lecture will be given on the unit of exposure doses and management methods of radiation exposure. Measurement method of radioactivity and radiation (1 time): A lecture will be given on the principle and usage of various radiation measuring devices. Regulation value of radiation (1 time): The concept of radiation protection, exposure limit value and risk, the method of setting an exposure limit value, the regulated value by law, methods to avoid radiation exposure, and so forth will be covered. Movement of radioactivity in the environment (1 time): A lecture will be given on the method of estimating the movement of radioactivity in the environment and exposure assessment. [Final exam] Feedback (1 time): Questions on the lectures or exams will be accepted and answered by E-mail. |
