Detection of radiation by a Geiger-Müller counter depends on
A)the emission of a photon from an excited atom.
B)the ability of an ionized gas to carry an electrical current.
C)the emission of a photon of light by the radioactive particle.
D)the ability of a photomultiplier tube to amplify the electrical signal from a phosphor.
E)the detection of the sound made by decay particles.

Question

Quizplus · Accepted Answer

A Geiger-Müller counter detects radiation by using a gas-filled chamber that becomes ionized when radiation passes through it. This ionization allows the gas to carry an electrical current, which is then detected by the counter. Therefore, the detection of radiation by a Geiger-Müller counter depends on the ability of an ionized gas to carry an electrical current.
