Chapter 10. Radiation Detectors[†]
† Suggestions by Glenn F. Knoll are recognized with appreciation.
Measurement of radiation is required in all facets of nuclear energy—in scientific studies, in the operation of reactors for the production of electric power, and for protection from radiation hazard. Detectors are used to identify the radioactive products of nuclear reactions and to measure neutron flux. They determine the amount of radioisotopes in the air we breathe and the water we drink, or the uptake of a sample of radioactive material administered to the human body for diagnosis. In recent years detectors have become important in frustrating terrorism.
The kind of detector used depends on the particles to be observed—electrons, gamma ...
