However, the Geiger–Müller tube produces a pulse output which is the same magnitude for all detected radiation, so a Geiger counter with an end window tube cannot distinguish between α- and β-particles. [4] A skilled operator can use varying distance from a radiation source to differentiate between α- and high energy β-particles.
The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It is named after Hans Geiger , who invented the principle in 1908, [ 1 ] and Walther Müller , who collaborated with Geiger in developing the technique further in 1928 to produce a practical tube that ...
The model is lightweight and water resistant, with an LCD display and a plastic case, along with miniature Geiger tube (shielded against beta particles), on a single, EMP-hardened, PCB. The PDRM was able to measure radiation dose rate in the range of 0.1 to 300 centiGrays. It was designed by Plessey to use three standard 1.5 volt cells, and is ...
The CD V-700M is a Model 6/6A/6B modified with an OCD-P-108 probe fitted with an OCD-D-109 GM tube that enables the detection of alpha radiation, in order to aid in decontamination. ENI 6B's were most commonly used, though some Victoreens were converted as well.
Ion chambers are preferred for high radiation dose rates because they have no "dead time"; a phenomenon which affects the accuracy of the Geiger–Müller tube at high dose rates. The advantages are good uniform response to gamma radiation and accurate overall dose reading, capable of measuring very high radiation rates, sustained high ...
However the Geiger counter can measure counts but not the energy of the radiation, so a technique known as energy compensation of the detector tube is used to produce a dose reading. This modifies the tube characteristic so each count resulting from a particular radiation type is equivalent to a specific quantity of deposited dose.
