Which of the following correctly describes a radiographic survey meter?

A radiographic survey meter is specifically designed to detect and measure radiation levels, making it a crucial instrument in industrial radiography. This tool is used to assess the presence and intensity of ionizing radiation in an environment, ensuring safety and compliance with regulatory standards. By measuring radiation levels, the survey meter helps operators ensure that they are within safe exposure limits while performing radiographic inspections.

The other options, while related to various aspects of measurement and safety, do not accurately describe the primary function of a radiographic survey meter. Unlike instruments focused on measuring electrical strength or those that serve as shielding in radiography, a survey meter's critical role lies in its ability to detect and quantify radiation, thereby providing essential safety information. Additionally, assessing film development time pertains to the photographic process rather than radiation measurement, reinforcing the specificity of the correct answer.
