GEIGER-MÜLLER DETECTOR Radiation DetectorsGEIGER-MÜLLER DETECTORThe Geiger-Müller detector is a radiation detector which operates in the G-Mregion.EO 2.6 DESCRIBE the operation of a Geiger-Müller (G-M)detector to include:a. Radiation detectionb. Quenchingc. Positive ion sheathThe Geiger-Müller or G-M detector is a radiation detector that operates in Region V, or G-Mregion, as shown on Figure 23. G-M detectors produce larger pulses than other types ofdetectors. However, discrimination is not possible, since the pulse height is independent of thetype of radiation. Counting systems that use G-M detectors are not as complex as those usingion chambers or proportional counters.Figure 23 Gas Ionization CurveIC-06 Page 42 Rev. 0
