Ionization chambers work on the principle that when radiation interacts with the electrons in air, ____ are produced.

Question

Quizplus · Accepted Answer

When radiation interacts with the electrons in air, they produce ion pairs - a positively charged ion and a negatively charged ion. An ionization chamber is a device that detects and measures these ion pairs. Therefore, choice A is the correct answer. Light scintillations are produced in scintillation detectors, scatter photons are a result of Compton scattering, and low energy x-ray photons are typically filtered out before reaching the ionization chamber.
