The primary function of a survey meter in radiography is to measure the radiation levels in an area. Survey meters are essential tools used in radiographic environments to ensure safety by detecting and quantifying radiation exposure. They provide immediate feedback on the level of radiation present, allowing personnel to make informed decisions regarding safety precautions and necessary protective actions.

By measuring radiation levels, survey meters help assess potential exposure risks for both workers and the surrounding environment. They play a crucial role in monitoring ionizing radiation to ensure compliance with safety regulations and guidelines, thereby protecting personnel from excessive radiation exposure.

The other functions listed, such as calibrating imaging equipment, assessing personnel exposure, and controlling the radiation source, are related to different aspects of radiation safety and management but do not encompass the primary role of a survey meter. Calibrating equipment and controlling sources typically require more specialized tools and procedures, while personnel exposure assessments often involve additional monitoring devices such as dosimeters.
