Summary
Gas detectors remain the most common and the most used of all detector types in experimental microdosimetry. This lecture aims to provide the basis for understanding gas detector operation and to illustrate their application in microdosimetry and radiation measurement science. The discussion will conclude with a review of future needs and current technical challenges.
