This class teaches the basics of radiation and its biological effects. It starts from the physical basis of radiation: what are alpha-ray, beta-ray, gamma-ray, X-ray etc and how their quantities are expressed. Next we learn the source and quantity of natural radiation exposure. Then we learn biological effects of radiation and its relationship to radiation dose. Finally we learn use of radiation in medical field and principles of safety use.
By the end of this class, student will be able to:
1) Explain the types and properties of radiations and how they are emitted or generated,
2) Explain the quantity and unit of radiation,
3) Explain the source and quantity of natural radiation exposure,
4) Explain the relationship between radiation dose and biological effects,
5) Explain how radiation is applied in the medical diagnosis and therapeutics,
6) Explain basic principles of safety use of radiation.
Radiation, Radioactivity, Biological effect, Cancer radiotherapy.
