What are the two types of dosimeters commonly used in radiological monitoring?

The correct answer identifies the two types of dosimeters commonly used in radiological monitoring as Optically Stimulated Luminescence (OSL) and self-reading pocket dosimeters. OSL dosimeters are widely utilized due to their sensitivity and ability to provide accurate dose measurements. They work by using a luminescent material where exposure to ionizing radiation causes the material to store energy, which can later be released as light when stimulated by a specific wavelength. This makes them useful for monitoring radiation exposure over time.

Self-reading pocket dosimeters, on the other hand, provide immediate feedback to the user about radiation exposure. These handheld devices allow workers to regularly check their radiation dose, enhancing on-the-spot awareness and safety measures.

In summary, this combination of dosimeters is crucial for providing both accurate long-term monitoring (through OSL) and immediate dose readings (through self-reading pocket dosimeters), which are essential for maintaining safety in environments where radiation exposure is a concern.
