| Health Physics Textbook, Chapter 12: Radiation Detection |
Per Hedemann Jensen et al., DD |
September 15, 2010 |
This chapter describes the physics associated with the detection of ionizing radiation using various types of detectors. Instruments employing gas-filled detectors such as Geiger counters and ionization chambers, as well as solid-state detectors like scintillators, semiconductor detectors, and dosimeters, are reviewed. Furthermore, the application of different detector types for measuring airborne radioactive substances is explained. |
