Which groups must wear a Dosimeter (TLD) according to the material?

• A. Those who can receive 10% of allowable dose
• B. Command directed personnel
• C. In field radiation environment
• D. All of the above

Answer: (D)

The main idea is that a dosimeter is worn by anyone who could receive occupational radiation exposure, so we can track and limit the dose they accumulate. If you can receive as little as 10% of the allowable dose, if you’re command-directed to perform tasks in potentially radioactive areas, or if you’re working in an actual field radiation environment, you have a real chance of exposure and need to be monitored. A TLD records the total dose over time, helping ensure regulatory limits are not exceeded and that ALARA principles are followed. Since all of these situations involve potential exposure, the correct approach is that all of the above groups should wear a dosimeter.
