A radioactive rock was placed on the detector causing the graph (in background) to rise. Gamma and X-Ray detectors generally use an "integral" design so the GeigerMller tube is conveniently within the electronics enclosure. For example, higher sensitive Geiger counter A counts 1000 particles while the B counts only 500 particles even though they measure the same object for 1 hour. It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a GeigerMller tube, which gives its name to the instrument. However, to facilitate more localised measurements such as "surface dose", the position of the tube in the enclosure is sometimes indicated by targets on the enclosure so an accurate measurement can be made with the tube at the correct orientation and a known distance from the surface. The first historical uses of the Geiger principle were to detect - and -particles, and the instrument is still used for this purpose today. For all the things this American-made GQ GMC-600+ digital Geiger counter can give, its price is really cheap. [1] However, the GeigerMller 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 - and -particles. [11] It superseded the earlier GeigerMller tube because of its much longer life and lower operating voltage, typically 400-900 volts.[12].
