What does the presence of a triangle symbol on a survey map indicate?

The triangle symbol on a survey map is typically used to indicate specific locations or points of interest related to radiation safety and monitoring. In the context of this question, the triangle symbol designates where air samples were taken. This information is crucial for assessing airborne contaminants or radiation levels in specific areas, as air samples can provide vital data about environmental conditions and potential exposure to radiation.

Understanding the context of air sampling is essential for radiation workers, as it helps them identify areas where monitoring was conducted and take appropriate precautions based on the results. By knowing where air samples were taken, workers can focus on areas that require more attention or further monitoring based on the potential risks indicated by those samples.
