The Geiger-Mueller (GM) detector is a common portable instrument option for a general study of laboratory radioactive materials. GM detectors are capable of detecting alpha, beta and gamma radiation. In nuclear medicine, it is necessary to determine the presence, type, intensity and energy of radiation emitted by radionuclides, and this is achieved by radiation detection instruments. The two commonly used devices are gas-filled detectors and scintillation detectors with associated electronics.

The main mobile instrument used to identify radiation in the environment is the gamma radiation detector. While gamma radiation is part of the normal background radiation of the environment, some places have higher levels of gamma radiation, either for natural reasons or due to human activities.
These activities can influence normal ambient radiation through the concentration of natural materials or as a result of an accident, during which radiation is released from a nuclear installation. The second major type of detectors used in radiation detection instruments are scintillation detectors. The miniaturization of computers makes it increasingly possible to use mobile instruments to detect and measure radiation. When talking about radiation detection instruments, there are three types of detectors that are most often used, depending on the specific needs of the device.
