WebDetection of Gamma Radiation using Ionization Chamber Gamma rays have very little trouble penetrating the metal walls of the chamber. Therefore, ionization chambers may be used to detect gamma radiation and X-rays, collectively known as photons, and for this, the windowless tube is used. WebFeb 13, 2024 · It does not require any ionization event to happen so that the tube must not be used in this region. The Geiger Muller counter can account for about 500 particles per second. The GM counter will not register those particles that pass through it in the dead time. Dead time refers to the time taken by the tube to recover between counts.
