What is the primary purpose of calibrating a survey meter?

The primary purpose of calibrating a survey meter is to ensure accuracy in dose measurements. Calibration is essential because it adjusts the survey meter's readings to reflect the actual radiation levels accurately. Over time, factors such as environmental changes, wear and tear, or battery variance can affect the meter's performance. By calibrating the instrument, users can confirm that the readings they receive correspond correctly to the actual radiation exposure levels present in the environment. This is crucial for ensuring safety in settings where radiation is present, as accurate measurements guide appropriate responses and protective actions. Reliable dose measurements are fundamental for compliance with health standards and regulations pertaining to radiation safety.
