How many monitoring devices should personnel wear, and what are they called?

The correct answer indicates that personnel should wear two monitoring devices: a Pocket Chamber and either a Film badge or a TLD (Thermoluminescent Dosimeter) badge. This practice is crucial in radiography to ensure accurate and reliable monitoring of radiation exposure among workers.

Having two types of monitoring devices provides a comprehensive approach to measuring radiation levels. The Pocket Chamber is a real-time device that allows personnel to continuously check their exposure and respond promptly if radiation levels rise unexpectedly. In contrast, the Film badge or TLD badge serves as a permanent record of exposure over time, allowing facilities to keep track of cumulative dose levels.

Using both types of devices enhances safety protocols, as it allows for immediate feedback and ongoing assessment of personnel's exposure to ionizing radiation, which is important for adhering to occupational safety standards. This combination is a well-established practice in the field to ensure robust radiation safety and compliance with regulations.
