Select the three items that are personal radiation monitors from the following list.

• A. Pocket dosimeter; Scintillation counter; G-M counter
• B. Scintillation counter; G-M counter; Thermoluminescent dosimeter
• C. Optically Stimulated Luminescence dosimeter; Thermoluminescent dosimeter; Personal Digital Ionization Chamber
• D. Optically Stimulated Luminescence dosimeter; Scintillation counter; Personal Digital Ionization Chamber

Answer: (C)

Personal radiation monitors are devices worn by workers to track the radiation dose they receive. Optically Stimulated Luminescence dosimeters and Thermoluminescent dosimeters are passive personal dosimeters that record dose over a monitoring period and are read later to determine the total exposure. The Personal Digital Ionization Chamber is an active personal monitor that provides real-time dose rate readings and accumulated dose while being worn. These three represent the common wearable monitoring options: passive dosimeters that store dose information, and an active device that gives immediate exposure data. The other instruments are used for area or survey purposes (not worn for ongoing individual dose), and a pocket dosimeter, while personal, is a direct-reading device rather than a stored-dose type, which is why the trio listed is the best fit for personal radiation monitors.
