What type of dosimeter provides reliable measurement regardless of moisture exposure?

The thermoluminescent dosimeter (TLD) is designed to provide reliable measurements of ionizing radiation exposure regardless of moisture conditions. This is because TLDs utilize lithium fluoride crystals, which are not significantly affected by moisture; they store energy from radiation exposure and release it as light when heated. This property makes them useful in various environments where other dosimeters might fail due to moisture sensitivity.

In contrast, film badges can be adversely affected by humidity, as moisture can fog the film, leading to inaccurate readings. Personal dosimeters can vary in functionality depending on their type and design; some may not perform optimally in wet conditions. Active electronic dosimeters are generally sensitive to environmental conditions as well, which can affect their reliability. Thus, TLDs stand out for their resilience in the presence of moisture, making them a preferred choice in many radiation safety applications.
