What happens when the lattice in TLDs is heated?

When the lattice in Thermoluminescent Dosimeters (TLDs) is heated, excited electrons that have been trapped in defect sites within the crystal lattice gain enough energy to overcome the energy barriers holding them in place. This allows them to fall back into their normal or ground state, a process that results in the emission of visible light. This light emission is measurable and correlates with the amount of radiation the TLD has been exposed to, making it possible to quantify the radiation dose. The heating process is crucial for TLDs, as it enables the release of stored energy in the form of light, which can then be detected and counted. The level of emitted light directly corresponds to the previous level of radiation exposure, allowing for effective dose assessment. This characteristic is what makes TLDs a valuable tool in radiation monitoring and protection. The other options suggest physical changes or losses that do not accurately describe the process occurring during heating within TLDs. The emission of light as a result of electron transitions is the key process at work when the lattice is subjected to heat.
