Track and Other Detectors

Track detectors (cloud chambers, bubble chambers, autoradiography, and solid — state detectors) can visualize the track of the radiation particles. They are mainly used in nuclear physical studies.

14.5.1 Cloud Chambers and Bubble Chambers

The Wilson’s cloud chamber is filled with supersaturated vapor (e. g., very pure alcohol vapor) in which liquid drops are formed under the effect of radiation. In this way, the trace of the radiation can be seen. The photos taken in cloud chambers have been shown previously in this book (e. g., Figures 4.11, 5.7, 5.14, 5.31, 6.1, 13.3, and 13.5).

Bubble chambers operate similarly, but the phases are opposite. Bubbles are formed in a superheated transparent liquid under the effect of radiation and visual­ize the track of the radiation particles.
