Which personal dosimeter provides a direct readout on the device?

• A. Pocket dosimeter
• B. Thermoluminescent dosimeter
• C. Optically stimulated luminescence dosimeter
• D. G-M counter

Answer: (A)

Direct-readout personal dosimeters are designed to show your exposure right on the device itself. A pocket dosimeter uses an ionization chamber worn by the worker and displays the accumulated dose immediately, so you can read it without sending it to a reader. Thermoluminescent dosimeters store energy and require heating in a laboratory reader to release light and read the dose. Optically stimulated luminescence dosimeters need a specialized reader that uses light to release the stored energy before a readout. A Geiger-Müller counter is a survey instrument that detects presence and rate of radiation rather than providing a personal, immediate dose measurement. So the pocket dosimeter is the one that gives a direct readout on the device.
