How often must rate alarms be calibrated according to radiation safety standards?

The requirement for calibrating rate alarms is essential to ensure that they function accurately and reliably. According to radiation safety standards, particularly those issued by agencies such as the National Council on Radiation Protection and Measurements (NCRP) and the U.S. Nuclear Regulatory Commission (NRC), rate alarms must be calibrated at least once a year. This annual calibration ensures that any drift in the instrument's response or sensitivity is corrected so that it can effectively warn personnel of potentially hazardous radiation levels.

Regular calibration helps maintain the integrity of the device's measurements and alarms, which are crucial for the safety of workers in environments where radiation is present. By adhering to the yearly calibration schedule, organizations can enhance overall radiation safety protocols, ensuring that alarms trigger at the appropriate radiation levels, thereby preventing overexposure.
