What type of dosimetry is used to measure the dose received from external sources?

• A. Thermoluminescent dosimetry
• B. Personal dosimetry
• C. Environmental dosimetry
• D. Scintillation

Answer: (A)

Thermoluminescent dosimetry is indeed a type of dosimetry used to measure the dose received from external radiation sources. This technique involves using materials like lithium fluoride, which absorb energy from ionizing radiation. When these materials are subsequently heated, they release the stored energy in the form of visible light. The amount of light emitted is proportional to the radiation dose received, allowing for accurate measurement of exposure. This method is particularly effective for individual or personal monitoring in environments where radiation exposure is a risk. Thermoluminescent dosimeters (TLDs) are often used in occupational settings to monitor personnel working in areas with potential radiation exposure, providing valuable data on the radiation dose received over time. In contrast, personal dosimetry focuses on measuring the radiation dose received by a person through various methods, which can include thermoluminescent dosimetry. Environmental dosimetry, while important, centers on measuring radiation levels in the environment rather than individual exposure, and scintillation typically refers to a different mechanism of detection that involves converting ionizing radiation into light to measure its energy rather than the dose received specifically.
