| Textbook Health Physics, Chapter 12: Radiation Detection |
Per Hedemann Jensen et al., DD |
15 September 2010 |
Describes the physics of detecting ionising radiation using different types of detectors. Instruments with gas-filled detectors such as Geiger chambers and ion chambers as well as solid-state detectors such as scintillators, semiconductor detectors and dosimeters are reviewed. The use of different detector types for the measurement of radioactive substances in air is also explained. |
