Geiger counters detect various types of radiation, including alpha, beta, gamma, and X-rays. The most common detector types are GM tubes (Geiger-Müller tubes) and scintillation detectors. GM tubes are simpler and more affordable but are limited to detecting gamma and X-rays. In contrast, scintillation detectors offer better precision and the ability to detect multiple radiation types but are more expensive.

Other types of radiation detectors include ionization chambers, semiconductor detectors, and proportional counters, each with its own strengths and weaknesses. Understanding the type of radiation you need to detect will help you choose the best Geiger counter for your needs.
