Which of the following is a common characteristic of a Geiger-Müller counter?

A common characteristic of a Geiger-Müller counter is that it can detect various types of ionizing radiation. This versatile instrument is widely used in radiation protection and environmental monitoring because it is capable of measuring alpha, beta, and gamma radiation. Its design allows it to interact with different types of ionizing particles, enabling it to convert radiation events into measurable electrical impulses, which can then be counted and displayed.

While options suggesting that it only measures alpha radiation or that it requires no calibration may sound appealing, they do not reflect the broader capabilities of the Geiger-Müller counter. The tool does require periodic calibration to ensure accuracy in readings, which contradicts the assertion of no calibration needed. The mention of color-coded readings pertains more to specific models or additional features rather than being a standard characteristic of all Geiger-Müller counters. Therefore, the ability to detect multiple types of ionizing radiation clearly distinguishes the Geiger-Müller counter as a comprehensive tool for monitoring radiation exposure.
