Which of the following is an advantage of using Optically Stimulable Luminescent Dosimeter (OSL) badges over Thermoluminescent Dosimeters (TLD)?

The advantage of using Optically Stimulable Luminescent (OSL) dosimeters over Thermoluminescent Dosimeters (TLD) lies in their increased sensitivity to radiation. OSL badges have a greater ability to detect low levels of radiation, making them particularly useful in environments where precise radiation monitoring is essential. The mechanism of OSL involves storing energy from ionizing radiation in a crystal matrix that can then be stimulated by light, releasing it in the form of luminescence. This property not only enhances sensitivity but also allows for a broader range of detection, even at lower doses.

While other factors such as cost, calibration, and durability might also differ between OSL and TLD badges, the significant advantage of sensitivity is crucial for effective radiation monitoring in many applications, particularly in healthcare and industrial settings where accurate dose assessments are paramount.
