What is a key advantage of OSL badges over film badges?

• A. Cheaper
• B. More sensitive and accurate and can be worn longer
• C. Requires less maintenance
• D. Only used in specialized facilities

Answer: (B)

A key advantage of OSL dosimeters is their higher sensitivity and accuracy across a wide dose range, plus the ability to be worn for longer periods. The optically stimulated luminescence material stores energy from radiation and, when read with light, releases a signal that can be measured precisely. This results in better detection of low doses and a broader dynamic range than film badges. Additionally, reads can be performed multiple times non-destructively and without chemical development, making results faster and more flexible. Because these readings are robust and can cover longer monitoring intervals, OSL badges can be worn longer between replacements while still providing reliable dose information.
