Which of the following is NOT a feature of TLDs?

The feature that is not characteristic of Thermoluminescent Dosimeters (TLDs) is the provision of instantaneous results. TLDs operate on the principle of measuring ionizing radiation by storing energy from radiation exposure in a crystal lattice. After exposure, they must be heated to release the trapped energy as light, which is then measured to quantify radiation dose. This process inherently requires a delay, as the dosimeter needs to be read out after the exposure is complete, rather than providing an immediate readout. While TLDs are designed to be reusable, capable of measuring ionizing radiation, and are compact in size, their main limitation lies in the need for this heating and reading process, which does not allow for immediate results. This characteristic is what sets TLDs apart from other monitoring devices that might provide real-time dose readings.
