Final answer:
The OSL dosimeter and the TLD operate based on stimulated luminescence, while the pocket dosimeter does not.
Step-by-step explanation:
Stimulated luminescence is a method used in several types of personal radiation monitors to measure radiation exposure. Of the options given, the OSL dosimeter (Optically Stimulated Luminescence dosimeter) and the TLD (Thermoluminescent Dosimeter) operate based on stimulated luminescence. OSL dosimeters use light to measure the charge in trapped electrons, which is proportional to the radiation dose, while TLDs measure the amount of light emitted from a crystal in the dosimeter when it is heated, which is also proportional to the radiation dose. The pocket dosimeter, on the other hand, operates differently; it uses a quartz fiber electroscopic sensor that measures the charge reduction resulting from ionization of the air within the dosimeter, and does not function based on stimulated luminescence.
