Which feature of the TLD badge makes it suitable for mixed radiation fields?

The feature that makes the TLD (Thermoluminescent Dosimeter) badge suitable for mixed radiation fields is its ability to give doses in such environments. TLDs can effectively measure exposure to various types of radiation, including alpha, beta, and gamma radiation. This capacity arises from the nature of the materials used in TLDs, which can respond to different radiation types by trapping energy from the radiation interactions. When heated, these materials release the stored energy in the form of light, which can be quantified to determine the dose received.

This flexibility makes TLDs particularly useful in mixed radiation fields where different radiation types are present simultaneously, allowing for accurate dose assessments that encompass contributions from all radiation sources.

In contrast, other features are less relevant for this specific application. For instance, the inability to be reused, energy dependency, and the complexity of calibration processes do not inherently provide the same degree of adaptability in mixed radiation exposure situations.
