| Textbook Health Physics, Chapter 1: Introduction |
Per Hedemann Jensen et al., DD |
15 September 2010 |
The textbook provides a comprehensive introduction to the many disciplines of health physics, from the physical description of radioactivity and ionising radiation, through protection principles and measures, to the biological effects of radiation. |
|
| Textbook Health Physics, Chapter 2: The World of Atoms |
Per Hedemann Jensen et al., DD |
15 September 2010 |
Summary. Provides a historical review of the atomic concept and explains the structure and physics of atoms, elements and isotopes, chemical reactions and the different phases of substances. |
|
| Textbook Health Physics, Chapter 3: Spontaneous Nuclear Transformations |
Per Hedemann Jensen et al., DD |
15 September 2010 |
Explains the concept of radioactivity and describes the different decay modes of radioactive nuclei. It also describes radioactive decay mathematically - including decay chains - and reviews the nuclide map in detail. |
|
| Textbook Health Physics, Chapter 4: Interaction of Ionised Radiation with Matter |
Per Hedemann Jensen et al., DD |
15 September 2010 |
Describes how ionising radiation interacts with all matter. Different types of ionising radiation are described. The interaction of these types of radiation with and energy transfer to matter is explained by the concept of interaction cross section, which also defines the range and attenuation of radiation in matter. The formation of braking radiation and characteristic X-rays is described. |
