What is a common use of a Geiger counter?

A Geiger counter is specifically designed to detect and measure ionizing radiation levels, making it a crucial instrument in various settings, such as in nuclear facilities, laboratories, and other environments where radiation is present. It operates by using a Geiger-Müller tube that clicks or produces a reading when radiation particles pass through it. The ability to provide real-time data about radiation exposure helps ensure safety and compliance with health standards, particularly in areas where radiation can pose a health risk.

In contrast, the other options involve measurements unrelated to radiation. Measuring temperature concerns thermal readings, assessing sound waves relates to acoustics, and calculating wind speed pertains to meteorology. Each of these fields uses specialized instruments that are not suitable for measuring radiation, highlighting the distinctive function of the Geiger counter as a dedicated tool for radiation detection.
