Which dosimeter is commonly used for radiation safety monitoring in a medical setting?

• A. Thermoluminescent dosimeter (TLD)
• B. Geiger-Müller counter
• C. Film badge dosimeter
• D. Personal electronic dosimeter

Answer: (A)

The thermoluminescent dosimeter (TLD) is widely used for radiation safety monitoring in medical settings due to its ability to provide accurate and reliable measurements of radiation exposure over time. TLDs work by absorbing energy from ionizing radiation, which is stored in the crystal structure of the material. When heated, the stored energy is released as visible light, and the intensity of this light can be measured to determine the amount of radiation exposure. TLDs are advantageous in medical environments because they offer a small, compact design that can be worn conveniently by healthcare professionals. They are sensitive to a broad range of radiation types and can be used for both dose accumulation and individual monitoring. Additionally, TLDs can be reused after they are read, providing a cost-effective solution for ongoing radiation monitoring. In contrast, other options such as Geiger-Müller counters are primarily used for detecting and measuring radiation in the environment or on surfaces rather than for personal dose monitoring. Film badge dosimeters, while they were historically common, have limitations in sensitivity and are less frequently used today in favor of TLDs. Personal electronic dosimeters are also available and provide real-time monitoring; however, they are generally more expensive and may not have the same level of
