What does an analog survey meter measure in terms of radiation?

An analog survey meter is designed to measure radiation exposure using a physical scale where the measurement is typically represented in units such as microsieverts per hour (µSv/h) or millirems per hour (mrem/h). These instruments gauge the rate at which ionizing radiation is interacting with the detector, providing a direct indication of the exposure rate experienced in a specific area.

The focus of an analog survey meter on measuring exposure rate allows users to assess the levels of radiation in their environment, which is vital for ensuring safety and compliance with radiation protection regulations. By understanding the exposure rate, users can make informed decisions about safety measures and necessary precautions.

Other options, while relating to the context of radiation measurement, do not align with the primary function of an analog survey meter. For instance, pulse rate pertains to the counting of individual radiation events, voltage level typically relates to the electrical functionality of the instrument rather than the radiation it measures, and radiation type identification generally requires different equipment or methods, such as spectroscopy. Thus, the choice regarding exposure rate accurately reflects the primary measurement capability of an analog survey meter.
