When should a dosimeter be calibrated?

Calibration of a dosimeter is essential for ensuring accurate measurements of exposure to hazardous substances or conditions. Regular calibration based on manufacturer guidelines helps to maintain the dosimeter's precision and reliability over time. The guidelines usually recommend specific intervals for calibration to account for factors such as drift, environmental conditions, and wear and tear that can affect the device's performance.

By adhering to the manufacturer's recommended calibration schedule, users can ensure that the dosimeter continues to provide accurate readings, which is critical for protecting worker health and complying with safety regulations. Calibration at regular intervals also allows for the identification and correction of any systematic errors that may arise, thus enhancing the overall effectiveness of occupational hygiene monitoring practices.
