The so-called "Cake-Pan Ionization Chamber" is used for the measurement of
-particle emission rates from very
large area sources, which themselves are used to calibrate surface monitoring
equipment. This is an air ionization chamber which operates at atmospheric
pressure. Since it is a current device, it measures total energy output
deposited in the chamber rather than radioactivity, per se.
