Which device provides a permanent record of your dose and has no electronic moving parts, cannot be read by the user?

• A. DLR
• B. SRD
• C. Dosimeter
• D. Shielding

Answer: (A)

The question tests understanding of passive dosimeters that leave a lasting dose record without user-accessible readouts. A device like this stores exposure in a material with no electronic moving parts, and the dose is retrieved later by processing rather than by the wearer. That description fits the passive dosimeter type used for permanent records, where you don’t read the dose yourself on site. The other options don’t match: a self-reading dosimeter is designed to be read by the user, so it isn’t read only in processing; a general dosimeter is a broad term and could imply a user-readable device; shielding isn’t a dosimeter at all and doesn’t provide a dose record.
