What are the advantages of using a thermoluminescent dosimeter?

  1. Large size and tissue response

  2. High sensitivity and cost-effectiveness

  3. Small size and tissue equivalent response

  4. Ease of use and wide availability

The correct answer is: Small size and tissue equivalent response

The advantages of using a thermoluminescent dosimeter (TLD) are primarily rooted in their small size and tissue-equivalent response. The small size of TLDs makes them particularly advantageous for applications where space is limited or where a minimal interferential mass is essential. This allows them to be utilized in various environments, including clinical settings, radiation therapy, and personal dosimetry for radiation workers. Their compact nature facilitates the monitoring of radiation exposure without significantly altering the scattering conditions in a radiation field. Additionally, the tissue-equivalent response of TLDs is crucial for accurate dosimetry. TLD materials are designed to closely mimic the absorption properties of human tissue when exposed to ionizing radiation. This characteristic provides reliable measurements of the dose received by individuals, allowing for improved patient safety and occupational health monitoring. As a result, they can more accurately represent the biological effects of radiation on living tissue, making them a preferred choice in many radiological applications. When considering other options, aspects like sensitivity and cost-effectiveness, as mentioned in one of the alternatives, are relevant. However, sensitivity can vary between TLD types, and cost-effectiveness may depend on specific applications and operational requirements. The emphasis on tissue-equivalent response is what
