In what situation is a radiation survey meter typically used?

A radiation survey meter is primarily used to measure radiation levels in an environment. This device detects and quantifies ionizing radiation, providing important data for ensuring safety in areas where radiation is present. It is essential for assessing potential radiation exposure to individuals in various settings, including medical, industrial, and research facilities. By monitoring radiation levels, safety officers can determine if the environment is within acceptable limits, allowing them to implement protective measures if necessary.

The other options do not align with the function of a radiation survey meter. Analyzing chemical compositions pertains to chemical analysis, which requires different instruments such as spectrometers. Regulating temperature is a function of thermometers or temperature controllers, and evaluating sound levels involves using sound level meters. Each of these tasks requires specialized equipment tailored to their respective measurements rather than a radiation survey meter, which is specifically designed for radiation detection and measurement.
