PPT-Lecture 9: Ionising Radiation Generation

Dr Sarah Bohndiek Learning outcomes After this lecture you should be able to Describe how ionising radiation is generated for medical imaging Explain the differences between an Xray tube and a linear accelerator. What about ionising radiation sources that are not work- related? We are all exposed to natural background radiation from sources outside of work, such as: the earth itself; cosmic radiation from Learning Objectives. I must be able to recall when ionising radiation is emitted. . I should be able to describe the three types of ionising radiation.. I might be able to explain the dangers of ionising radiation.. .

What type of radiation is most harmful It depends on whether your exposure to radiation is internal or external beta particles Radioactive materials thatRadiation can affect the bodyThese adverse hea Lecturer Radiology INU. What is radiology?. Radiology is a branch of medicine that uses imaging technology to diagnose and treat disease.. Radiology may be divided into two different areas, diagnostic radiology and interventional radiology. Doctors who specialize in radiology are called radiologists.. The cell life cycle The cell cycle G0 = Cell is resting G1 = RNA and proteins are made S = DNA is made G2 = Apparatus for mitosis is built M = Mitosis (the cell divides into 2 cells) G0 phase (restin 231 Vol. 25, No. 5: 231–242 Contamination of food with microorganisms, particularly pathogenic non-sporeforming bacteria, is one of the most significant public health prob - lems and an importa Exposure.

Secondary exposure:. . Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . •. Radiation biology . is the study of the action of ionizing radiation on living organisms . •The action is very complex, involving physics, chemistry, and biology . –Different types of ionizing radiation .
