What device is used as a standard for comparison with personal dosimeters?

• A. Calibration monitor
• B. Control badge
• C. Lead apron
• D. Exposure recorder

Answer: (B)

The correct answer is a control badge. A control badge is a device used to monitor background radiation levels in the environment and serves as a standard for comparison with individual personal dosimeters. It is typically kept in a location that is free from exposure to radiation directly affecting the dosimeters worn by personnel. By comparing the readings from the control badge with those from the personal dosimeters, it is possible to determine if the personal dosimeters have been exposed to additional radiation during use. Calibration monitors, while important for ensuring the accuracy of the dosimeters, are not used as a standard for comparison in the same manner as control badges. Lead aprons serve to protect individuals from radiation exposure but do not provide measurable data for dosimetry purposes. Exposure recorders track radiation exposure but do not function as a standard for comparison. Thus, the control badge plays a crucial role in verifying the accuracy of radiation monitoring for individual workers.
